When I see E2EE and XMPP mentioned, I think of this blog post by Soatok, outlining some very odd cryptographic choices in XMPP + OMEMO: https://soatok.blog/2024/08/04/against-xmppomemo/

I would very much like to see a richer playing field than just Signal for private messaging, but it's a tough nut to crack. For exactly which aspect that turns me away from XMPP for E2EE, I think this nails it down:

you only need check whether OMEMO is on by default (it isn’t), or whether OMEMO can be turned off even if your client supports it (it can).

When the competition is Signal, these sorts of details matter a lot.

have you looked at simplex? at a glance it seems robust and it actually works without much fiddling which is nice.

I have experimented with Simplex, but it feels less tuned toward hosting federated infrastructure and more tuned toward participation with the greater network in a pseudo-anonymous fashion.

Adoption is also always a hurdle with any ecosystem like this, and XMPP is certainly ahead of Simplex in that avenue.
