I think AP will just be used as account authentication/creation with Signal software as the backend, but this is speculation.

“you will be able send Signal/Matrix messages from your fediverse instance of choice”

While no details are clear, it’ll definitely not be this. Matrix has it’s own implementation which isn’t compatible with signal (megolm or something like that), and I really don’t think dansup will be making it matrix compatible. It’ll probably be its own thing.
