Remove the `.well-known` resolution rule

[OR13]

This issue is raised to discuss potential breaking changes to the resolution rules for did web.

I propose we remove the .well-known resolution rule, and instead handle resolution for naked origins as follows:

did:web:example.com - > https://example.com/did.json

This is just another case of the existing path based routing resolution rules...

A 302 redirect can be configured to preserve any existing did documents.

This would simplify the did to url conversion logic by 50% with no loss of the name space.

A Well Known URI (RFC 8615 ) for a domain-wide DID would enable a sort of DKIM capability via DID, which I think could have considerable value.

I see that /.well-known/did.json is not currently in the registry.

Are we anticipating that the registry entry will not be forthcoming?

[OR13]

@gribneau certainly we would need to register it if we continue to use it.

I don't think we loose any potential features by opting not to use .well-known URIs though... there are similar situations today, for example https://github.com/OR13.gpg

[gribneau]

The usage of .well-known predates my involvement. I suppose I assumed that it was already registered or that registration was imminent.

If no registration is underway, we should not use it.

:+1: I'm on board with simplifying the "domain-only" resolution rules to drop the .well-known/ part.

I agree with this comment by @tplooker and would 👎 dropping .well-known/.

The did:web ID is machine-translated into a HTTPS URI for automated GETs, it's not intended to be a directly fetch-able URI itself (IMO).
