I would like to hide all client-side decorations in Gnome, by setting a GSettings override.
I am aware of one SO answer, which is unsuitable because it targets extension developers.
I am also aware of the undecorate extension, but besides not being supported in newer versions of gnome, this doesn't remove decorations across the board by default.
So - I would like a solution which just uses a GSetting override or otherwise fully disables decorations.
