xlibre has a number of developers working on it (more than most Wayland projects). One of them is stefan11111 who has in the past done some great work at cleaning up fundamental libraries (i.e gtk+2).So, it might affect the quality of his software. It defintely make me feel suspicious when he says how he was silenced.
Speaking of which, there is even more interest for X11 and Gtk+2 in recent weeks.
