Description
It's maybe too soon to consider this here, but..
There are a few recent standards that started including key committing AEADs, notable anything extremely low-entropy like OPAQUE.

There remain some gaps in the literature, like encrypt-then-MAC with either a KDF or KEX that yields a common encryption and MAC key sounds more committing than any of those articles indicates, and is already fairly standard practice.

Research direction
The issue names no source files, tests, or entry points; start by reading the three linked papers and the discussion of low-entropy key commitment. Done would require an agreed scope for supporting key-committing AEADs and a concrete implementation target, neither of which is specified here.
