Just share the screen/tmux session on a server. We already had realtime collaboration.

I agree. I'm staring at the use-cases for sharing and don't understand what this does any better than tmux/tmate

If I want to save a session, I use tmux. If I want to share that session, I use tmate.

I can also self-host tmate on my own machines which makes it even more attractive.

I think some of the session stuff is nice, but it's not for me.
