That's not the norm
It will never be compatible with X because they are different designs. X relies on a central program (server) that accepts commands from programs. It is also a mess as it was built during the 80s for 80s hardware. It was expanded over time but you can only stretch the arch so far.
Wayland doesn't have a server. You desktop talks to the hardware and then the desktop accepts connections from apps.
It was nice while it lasted (not)
You probably could do this outside the carrier
XMPP sucks for me
If it works for you that's great but it won't work for everyone. XMPP lacks coherency and is kind of a mess. Matrix isn't perfect but at least there is a central direction. It also has companies that provide commercial services which is nice although I wouldn't trust it in prod right now.
I love that this is the only comment
I don't get it. Why do you want a benchmark?
We will need to watch closely because this might be a experiment that only applies to a few people.
Are you surprised by this? It is SMS after all. I think you could do this with a basic man in the middle.
"Secure from our competitors"
I think the desktop itself does that. For instance Gnome is working on accessibility
