@nprofile1q... @nprofile1q... I think Prāv (which is a fork of Quicksy) was interested in working on that.

But you’re missing the point - XMPP gives you freedom of service providers. You don’t have to use Quicksy or Prāv, not even to talk to Quicksy or Prāv users. You could use any of the many public servers, or host your own to have even stronger guarantees than Signal.
