Sometimes I wonder if the endgame is each person having their own XMPP server for their set of devices. S2S is your E2EE then. Your chain of trust is your existing CA, unlike Matrix which starts from scratch. Cause XMPP wasn't designed from the start for clients not to trust servers, plus the fragmentation of C2S extensions was always a pain.

It's not a bad solution if someone can make it easy, even if it's a managed service that just lets tech-savvy users export it to self-hosting if they want.
