veda deficiencies

Incompleteness

वेदा अपूर्णा इति ते स्वयं वदन्ति। तेन वेदभिन्नान्य् अपि शास्त्राणि यथोचितं ग्राह्याणि स्युः।

Irrelevant bits

On vaidika (kAmya) karma-s vis-a-vis mokSha and pravRtti-dharma: यामिमां पुष्पितां वाचं प्रवदन्त्यविपश्चितः। … यावानर्थ उदपाने सर्वतः संप्लुतोदके। तावान् सर्वेषु वेदेषु ब्राह्मणस्य विजानतः॥2.46॥ [2.46 note]

Continuity with later literature

The development of brAhmaNa-s continued into shrauta and gRhyasUtra-s. The latter are terse, but the former is not. The oldest shrauta-sUtra - baudhAyana is long like the brAhmaNa-s causing him to be called a pravachanakAra. A late brAhmaNa - the vAdhUlasa anvAkhyAna is indeed termed an anvAkhyAna.

Veda-Equality claims

Within sectarian limits, some non-vaidika shAstra-s may be considered equal to the veda-s in authority (especially with regards to upAsana if not dharma).

pAncharAtra-Agama by vaiShNava-s.
Some verses which praise the purANa-s and itihAsa-s (in their original form, which isn’t available to us) as equivalent to veda-s are taken quite literally for rhetorical and practical purposes.
Eg. itihAsa and mahApurANa are Apaurusheya (= Ishvara-kRta) according to Gaudiya Vaishnava philosophy propagated by Shrila Jiva Gosvamipada in his celebrated 16th Century CE work ‘Tattva-sandarbhah’ & by Shri Vallabhacharya in Tattvarthadipanibandhah. (“न चावेदेन वेदस्य बृंहणं संभवति न ह्यपरिपूर्णस्य कनकवलयस्य त्रपुणा पूरणं युज्यते ।”)
(श्रीमद्भागवते ३.१२.३७) च – “…ऋग्यजुः सामाथर्वाख्यान्वेदान्पूर्वादिभिर्मुखैः।” इत्यादिप्रकरणे (श्रीमद्भागवते ३.१२.३९) – “…इतिहासपुराणानि पञ्चमम् वेदमीश्वरः। सर्वेभ्य एव वक्त्रेभ्यः ससृजे सर्वदर्शनः ॥“
एवं वा अरेऽस्य महतो भूतस्य निःश्वसितमेतद्यद्ऋग्वेदो यजुर्वेदः सामवेदोऽथर्व्वाङ्गिरस इतिहासः पुराणम्।
छान्दोग्योपनिषदि च (७.१.२) – “ऋग्वेदं भगवोऽध्येमि यजुर्वेदं सामवेदमाथर्वणम् चतुर्थमितिहासं पुराणं पञ्चमं वेदानां वेदम्”

rAmAyaNa case

rAmAyaNa was said to be created in order to elaborate on the veda-s. This effort was expressed in several ways:

several shloka-s in rAmAyaNa and commentaries
noting the use of the letters of the gAyatrI mantra at regular shloka intervals
creation of works like mantrarAmAyaNa (archive)
