FYI: Dave Longley has suggested a potential workable proposal.  I will look
into this a bit more, but it seems promising.

Pending this being a workable compromise, I withdraw my -1

So long as we can keep our canonical URIs in nostr, prepending a short
prefix in the VC proofs does not strike me as a great hardship, as we dont
have a solution in this space right now, new libraries can be written.  I
just need to verify this will work with nostr schnorr signatures and nonces.
