@thisismissem @evan alternatively having a "DM-native" protocol handle DMs – whether that's Signal or another protocol, it would be *trivial* to point a webfinger profile (or mastodon profile, but it'd be nice if this worked across different AP implementations) at a Signal account and let that other system handle it. Also adding developer-parseable support for DMs to AP would be trivial (except for all the encryption, so not really trivial ;-) ). Remember: we made all this up. It can change!
