Rama was not only capable of withdrawing weapon but also guiding his weapon in his desired trajectory. You don't find Brahmastra chasing someone in three worlds in the Mahabharata.
This is from Kishkindha Kandha
स विसृष्टो बलवता बाणः स्वर्ण परिष्कृतः | भित्त्वा सालान् गिरि प्रस्थम्
सप्त भूमिम् विवेश ह || ४-१२-३
The golden arrow released by the mighty Rama perforated all the seven
sala trees, and even the leveled areas of the mountain, and then
entered the earth. [4-12-3]
सायकः तु मुहूर्तेन सालान् भित्त्वा महाजवः | निष्पत्य च पुनः तूर्णम्
तम् एव प्रविवेश ह || ४-१२-४ .
Thus that arrow which briskly drilled all the sala trees came up in a
moment from under the earth, and again swiftly re-entered the quiver
of Rama. [4-12-4]
That arrow not only drilled one tree as asked by Sugreeva, but all the seven, and also a mountain from peak to core, and even entered the seventh earthly plane, that which is beneath the sixth plane of the earth, where atala, vitala, sutala, paataala, rasaatal, talaatala are the names of six strata of earth.
Not ONLY Rama but Ravan's Brahma weapon was also guided missile.In Sarga 59 of Yuddha Kanda, the divine Brahma spear hit Lakshmana and returned to his chariot.
Rama didn't revoke Brahmastra in Jayanta case because Jayanta hurt Sita. Revoking Brahmastra without punishing him was tantamount to injustice.
The verses in Yuddha Kanda where Rama didn't revoke Brahmastra against ocean is NOT in the critical version of Valmiki Ramayana. So I'll NOT comment.
The third argument is not revoking Vaisnava divine weapon against Parshurama.
न हि अयम् वैष्णवो दिव्यः शरः पर पुरंजयः | मोघः पतति वीर्येण बल
दर्प विनाशनः || १-७६-८
"This Vishnu's divine arrow is the conqueror of opponents'
citadels, and a vanquisher of their vigour and vainglory, and it will
not fall through wastefully... isn't it!" So said archer Rama to
axeman Rama. [1-76-8]
The fact of the matter is that Vaisnava astra is infallible. Lord Krishna saved Arjuna from Vaisnava astra in the Drona Parva of the Mahabharata.

his arrowy down-pours. Partha then cutting off his bow and quivers,
quickly struck him with two and seventy shafts, afflicting his vital
limbs. Thus pierced, he was excessively pained. Filled then with rage,
he with Mantras, turned his hook into the Vaishnava weapon and hurled
it at Arjuna's breast. That all-slaying weapon, hurled by Bhagadatta,
Kesava, covering Arjuna, received on his breast. Thereupon, that
weapon became a triumphal garland on Kesava's breast. Arjuna then
cheerlessly addressed Kesava, saying, 'O sinless one, without battling
thyself, thou art to only guide my steed! Thou hadst said so, O
lotus-eyed one! Why then dost thou not adhere to thy promise? If I
sink in distress, or become unable to baffle, or resist a foe or
weapon, then mayst thou act so, but not when I am standing thus. Thou
knowest that with my bow and arrows I am competent to vanquish these
worlds with the gods, the Asuras, and men.' Hearing these words of
Arjuna, Vasudeva replied unto him, saying, 'Listen, O Partha, to this
secret and ancient history as it is, O sinless one! I have four forms,
eternally engaged as I am in protecting the worlds. Dividing my own
Self, I ordain the good of the worlds. One form of mine, staying on
the earth, is engaged in the practice of ascetic austerities. Another
beholdeth the good and the evil deeds in the world. My third form,
coming into the world of men, is engaged in action. My fourth form
lieth down in sleep for a thousand years. The form of mine which
awaketh from sleep at the end of a thousand years, granteth, upon
awakening, excellent boons to persons deserving of them. The earth,
knowing (on one occasion) that that time had come, asked of me a boon
for (her son) Naraka. Hear, O Partha, what that boon was. Possessed of
the Vaishnava weapon, let my son become incapable of being slain by
the gods and the Asuras. It behoveth thee to grant me that weapon.
Hearing this prayer, I then gave, in days of old, the supreme and
infallible Vaishnava weapon to the Earth's son. I said also at that
time these words, 'O Earth, let this weapon be infallible for the
protection of Naraka. None will be able to slay him. Protected by this
weapon, thy son will always, in all the worlds, be invincible and
crush all hostile hosts.' Saying, So be it! the intelligent goddess
went away, her wishes fulfilled. And Naraka also became invincible and
always scorched his foes. It was from Naraka, O Partha, that the ruler
of the Pragjyotishas got this weapon of mine. There is none, in all
the world, O sire, including even Indra and Rudra, who is unslayable
by this weapon. It was for thy sake, therefore, that I baffled it,
violating my promise. The great Asura hath now been divested of that
supreme weapon. Slay now, O Partha, that invincible foe of thine,
viz., Bhagadatta, enemy of the gods, even as I formerly slew for the
good of the worlds, the Asura Naraka.' Thus addressed by the
high-souled Kesava, Partha suddenly overwhelmed Bhagadatta with clouds
of whetted arrows. Then, the mighty-armed and high-souled Arjuna
fearlessly struck a long arrow between the frontal globes of his
enemy's elephant. That arrow, splitting the elephant like the thunder
splitting a mountain, penetrated into its body to the very wings, like

Vaisnava weapon was Amogh. So revoking it doesn't make sense
