This is tying key value pairs to an identifier.

Nice idea, it's asking a notary to sign key value pairs associated with a
key pair, tho satoshi did specifically create bitcoin to remove trusted
third parties to bring down the cost of finance

there's case insensitive strings that can be derived from a bitcoin public
key (which also derives the address)

But you could simply make a document with the KYC fields tied to a bitcoin
URI then pay notaries to sign that.

Love the idea of reusing TLS and domains for identity.

But be aware that this is one approach of many.  The idea of "global"
should be that it is inclusive, not narrowed down by the spec.  This is why
using anyURI, neatly solves that problem.
