As others have mentioned, this is a false impression. Many of those 8
implementing organizations have customers other than DHS.

For example, the National Association of Convenience Stores will be using the
VC HTTP API for their TruAge program:


You will note that a key goal of that program is customer privacy, control,
and agency over their digital wallets. This is why the program has picked
Verifiable Credentials, Decentralized Identifiers, and yes, the VC HTTP API to
provide a large chunk of the functionality that is needed in the system.

Other customers exist (that are using the VC HTTP API) in the supply chain,
banking, insurance, and retail environments.

It's not irrelevant. There is no authorization mechanism defined for the VC
HTTP API specification. You are saying that OAuth2 is fine for those use
cases, yet at the same time are opposed to making proposals to that effect.

If we ran this proposal, would you +1 it?

PROPOSAL: At least one authorization mechanism for internal VC HTTP API calls,
that is calls in the same trust domain, will be OAuth2.

If you were able to +1 that, we'd be well on our way to real progress here.

Will you +1 the proposal above, Adrian?
