I am not sure how I feel about it but there seems to be some resistance in the GTK world. Desktops like Cinnamon,MATE, and XFCE have said they are going to stick with GTK3. Mint has proposed a common suite of GTK3 apps called Xapps that would maintain GTK3 versions of some of the applications that GNOME has pulled to GTK4.

One of the best things about the GTK world was that you had a choice of DEs but got the same universe of “native” applications with any of them. Sadly, it seems that there may now be GNOME and “other GTK” DE universes. On the plus side, there will be a haven for those that want off the GNOME train without as much “left behind” feel as MATE users have had.
I don’t love the default XFCE look but the default in distros like EndeavourOS or CachyOS are awesome. It is like a totally different DE.
