On the contrary, I'd love to see the VCs for JSON-LD community move
forward, in particular as I'd like to see more focus of a variety of issues
at the VP levels, more designs that leverage selective disclosure (in
particular mandating at minimum the use of the emerging Merkle Disclosure
LD proof), and focus deeper into requirements of the use of key material
and security of code.

It is what feels like a 5-year quixotic attempt to unify with JWT that I'd
like to move past, especially as even that isn't good enough, as advantages
of going beyond JWT integration to leverage modern cryptography, support
other kinds of structured data models and herd privacy, opportunities of
CBOR-based structures, etc. meet other needs. Maybe a VC 3.0 can solve them
all, but it doesn't feel like VC 2.0 has time.

I really hope you'll articulate responses to my architectural points — but
I REALLY don't necessarily feel that you have to address them in VC 2.0.
However, the quest to achieve "one data model for all" in the limited time
VC 2.0 has feels misguided.
