I've started reading up on #ActivityPub. So far I had been assuming that the "@user@host" scheme was baked into the protocol, but apparently it isn't, and it's perfectly capable of integrating user-less domains into the Fediverse.
Have I misread it? (I admit I only did surface level reading so far.)
If I haven't, wouldn't this mean that instances could (theoretically) also just act as hosting providers for #IndieWeb style domain-as-identity accounts?
@aaronpk That sounds bad :( If a site implements the spec version of ActivityPub, what are its chances of being feasibly well integrated into the Mastodon part of the Fediverse?
