Jabber/XMPP is now over 25 years old. Its peak was back when Google Talk and Facebook Chat adopted it in the late 2000s and when Whatsapp launched using XMPP under the hood. And it largely died when those two large companies went fully proprietary around 2015.

The fact that 25 years later it's still being described as two completely different names with a slash between them ("Jabber" SLASH "XMPP" ) makes me pretty confident it's not coming back.

Don't get me wrong...I'd love open, interoperable chat that everyone is reachable by as much as anyone, but it's important to recognize when one approach isn't working and why it isn't.

There's a lot of lessons to be learned from the death of jabber which I outlined in a post back on 2019: https://larrysalibra.com/the-death-of-jabber/
