They claim 30 developers right now. Don't know if true and if they are any good, but when the time comes to update my xserver, I will have a look at them - just to show my support.
Ah aeh, Wayland, it too got pitched to me recently. But I don't see it improves on any use case I have, but actively disables functionality I need. So a big no go and pass. Why should I change anything in my single-user distro - thank you.
Some of us thought to ourselves in the 90s, I don't have to use Windows. There is something called Linux. I remember installing SUSe from 5 1/4 floppies (A LOT of them) and configuring scanlines and hoping my CRT survives the first startx command. I gave no one authority to say what get's deprecated and what not to me. The only person who can do this I am myself.
I use Linux because of people back then as Linux Torvalds and today Jordan Sissel, who do the right thing out of passion and not expectation of financial or other reward. Just for themselves and then share it, because it might be useful for others too. It's not a 9 to 5 job to them.
People like Lennart Poettering or some other kids who want to coax me into accepting their toys are a reason for me to run away as fast as possible from such shenanigans. I survived editing the scan lines, I don't need software from IBM.
Regarding Wayland and GUIs: GUIs have been much worse than command line and batch environments for automation. xdotool is kind of the best we have (basically just creating macros like in an editor for the whole system), but neither X11 nor the applications are really designed for automation. AppleScript and d-bus all kind of never really worked out. What will happen now with text based gen-AI models, we will go back to good old text (plus speach) interfaces. We will just tell (e.g. in a text box) the AI what we want and they find a way to deliver whatever it is we asked for. Then finally the AI properly controls a web browser for us, but we don't need to see any of that.
