I will preface this with, I may be wrong, but as I understand it xmpp is just a protocol. One that, unless it’s been revised, imparts no encryption at all. Signal, and Session, are full architectures that enable all of the afrementioned features from my initial post including server and client.
Everything you might use relies on a protocol down the stack. XMPP happens to be the only one to date that is an internet standard (IETF), is extensible by design (past/present and future use-cases can be build into it, what makes it still relevant 25 years later), is federated (but not P2P, a good trade-off for mobile usage), has a diverse/multi-partite ecosystem of client and server implementers (sustainable and resilient), and is deployed successfully at scale (on billion of devices).
Sure, now which pre-existing piece of xmpp based software checks all the feature boxes as noted by both Signal adherents and myself regarding Session? Are you implying the lay user code their own? If that exists you could have just linked to it rather than engage in whatever this is.
Use Session instead. Open source, E2E encrypted, onion routed, no phone numbers. https://getsession.org/
Audited too. https://blog.quarkslab.com/resources/2021-05-04_audit-of-session-secure-messaging-application/20-08-Oxen-REP-v1.4.pdf
So, what would be the appeal compared to XMPP?

Today’s XMPP uses the same E2EE as Signal/WhatsApp/Matrix/… XMPP had end-to-end encryption 10 years before Signal was invented
