I'll take a shot at answering over email. :)

Data Integrity for BBS (BLS12-381) has been on the standards-track in
the W3C VCWG for 2+ years now, and is in the Candidate Recommendation
phase currently:

https://www.w3.org/TR/vc-di-bbs/

We are waiting on cryptographic review to complete on the BBS specs at
IETF to move the specification to Proposed Recommendation. Due to the
nature of cryptographic review at IETF's CFRG, we don't have a
timeline (because none is given; it'll be done when it's done). I will
note, however, that cryptographic review has already been completed
(and passed) for the base BBS specification and we're just now waiting
for that review to complete for the Blind BBS and Pseudonym
specifications. If I had to take a wild guess, I'd say that 75% chance
that it will be done by the end of the year.

I am not aware of any work to generate a Data Integrity cryptosuite
for SM2, but we tend to not get requests like that (to add SM2 key
description) unless there are already people working on it.

The design, implementation, and deployment of Data Integrity
cryptosuite specifications is decentralized, so it's not possible for
us to know about every type of Data Integrity cryptosuite that people
might be developing. All we know is that someone wanted us to specify
the key format, and usually they don't do that unless they're also
working on a cryptosuite. :)

Did that answer your question, David?
