> worst Canonicalisms
Do the Mint team treat fixing the other half of the problem, the GNOMEisms, as out-of-scope?
Asking because I maintain my own pile of gsettings and .gtkrc tweaks as mitigations yet pain points remain, apparently unfixable outside the source code.
Their approach to GNOMEisms is to officially support three desktop editions: Cinnamon (based on GNOME 3), MATE (based on GNOME 2), and Xfce (based on more recent Gtk). I don't think they try to tame modern GNOME, and I wouldn't expect them to, since that would be an endlessly difficult moving target.
If you want more detail, you should ask someone who still uses Gtk-based desktops, or try them yourself. I gave up on Gtk a couple years ago.
