I don't have much skin in the game to be honest because I've given up on using any GUI apps on Linux wherever possible. If I do use GUI apps, I keep looking for ways to quit using them too. The attitude exhibited by GTK and GNOME developers on their issue trackers and the unstable nature of KDE apps on Wayland has made me cynical about GUI on Linux.
I wouldn't know how to differentiate between "supported" and "unsupported" features on GNOME. If basic features like changing keyboard shortcuts are "unsupported" on GNOME, I'm not sure who the target audience of such a DE is, except maybe grandmas, managers, and people with attention deficit issues. Then again, I fail to see why such people would bother with using Linux in the first place.
And yeah, I would use KDE apps but they're almost unusable on swaywm on Wayland so I've stopped using them as well.
I'll focus on creating and using only command line tools and TUIs. Unlike the GUI mess that we have, they are mostly platform independent and can be used almost anywhere.
It was nice talking to you. Thanks for your time.
