You can absolutely convert a did:key to a did:btrc, or a did:ion or
did:elem for that matter... in fact, you could start with a did:key and end
with a did:v1, did:peer, did:ion and did:elem.... and if we can ever agree
on the concept of https://www.w3.org/TR/did-core/#equivalence we could link
them all :)

I'd love to collaborate on did:torv3 please link a repo if possible.
