I know there is a lot of that, but doesn’t RH also fund a LOT of gnome development?
I mean, this is a worse argument. It’s saying “How dare you not volunteer your free time or paid time to meet my priorities even though it’s not your priority or the priority of the people who are paying you”.
XFCE and MATE are going to be slow on the uptick since GTK4 isn't a desktop toolkit at the moment. From what I understand, it has the potential to be, but the maintained haven't opened up certain APIs.
As for the desktop environments, okay, so Elementary uses Gtk4 too. That's GNOME and Elementary. 2 of them. And we're ignoring all the applications that still use gtk3 (or 2) and the very few of them that have ported to Gtk4 (since the docs aren't even finished for 4).
As for the docs, it was when I last checked about 5 months ago.
Silly tribal nonsense that applies to more than a few maintainers and software.
