My answer is based on vedas which says lord Indra is the name of supreme Brahman or supreme reality -:
Indra is called as the Lord of the Universe, the all pervader and the Supreme Lord in many Vedic verses. Here are some examples from RigVeda:
रूपं-रूपं परतिरूपो बभूव तदस्य रूपं परतिचक्षणाय | इन्द्रो मायाभिः पुरुरूप ईयते युक्ता हयस्य हरयःशता दश || (RigVeda 6.47.18)
In every figure he hath been the mode: this is his only form for us to look on. Indra assumes many form by his Maya, for his Bay Steeds are yoked, ten times a hundred.
यो विश्वस्य जगतः पराणतस पतिर्यो बरह्मणे परथमो गा अविन्दत | इन्द्रो यो दस्यून्रधरानवातिरन म... || (RigVeda 1.101.5)
He who is Lord of all the world that moves and breathes, who for the Brahman first before all found the Cows; Indra who cast the Dasyus down beneath his feet,—him girt by Maruts we invoke to be our Friend.
At HSE too, we have
Which Vedic verses describe Indra as Brahman?
To non-sectarian Hindus, there is no need to "re-interpret" these direct statements. Most deities have done questionable things and incidents like Ahalya (many consider it an interpolation) need not take away from Indra's supremacy.
Are there sectarian reasons behind belittling Indra as a mere post?
EDIT: this question is not asking for pros and cons of saying "Indra is Brahman".
It is asking which sects would find their foundational doctrines questioned if Indra is Brahman.
