According to @Excellion, OP_RETURN2 is a potential Bitcoin soft-fork concept proposing a cheaper, fully discardable OP_RETURN2 annex not included in transaction hashes, limiting OP_RETURN via consensus rules, and removing the SegWit discount. Source: https://x.com/Excellion/status/1974608749429137533 Removing the SegWit discount would increase the effective weight of witness data toward 4 weight units per byte (like base data) from the discounted 1 weight unit, directly raising fees for witness-heavy transactions per the BIP-141 weight formula.
