XMPP doesn’t change very very often, but there’s actually tons of XEPs that are in common use and are considered functionally essential for a modern client, and with much higher numbers than XEP-0004

The good news, though, is that mostly you as the user don’t need to care about those! Most of the modern clients agree on the core set and thus interoperate fine for most normal things. And most XEPs have a fallback in case the receiver doesn’t support the same XEPs.

I’m general XMPP as a protocol is a lightweight core that supports an interesting soup of modules (in the form of XEPs) to make it a real messenger in the modern sense. And I think that’s neat! But you can’t really judge the core to say how often things change.

They’re taking about switching to Jabber/XMPP, which is what those two bridges are for, and they’re saying XMPP servers are lightweight.

It’s a bit confusing in context, I’ll admit.

Hmmm… for reasons I cannot justify my brain is telling me the equivalent for “my man, you really blah blah blah” should be “madame, you really blah blah blah”

Though I agree you can’t correct someone by being like “ahem, it’s madame actually” 😛
