You’re in a rather special position regarding the extensions in this case because except for 3 of them, they’re all directly maintained by your distro of choice. Which, additionally, is super slow with updating due to focusing on getting Cosmic ready and therefore extremely stable (and outdated) given nothing changes.
Distro-specific extensions really are one of the few places where this kind of unstable extension system makes sense, since your distro maintainer also controls the update flow of Gnome for you and can do proper QA on it w/ those extensions before making updates available. It’s not a mix’n’match of code.
Also, I do realize that theming on Gnome isn’t officially supported on an OS level, and I don’t fully understand it all, but I do have a fairly consistently-used custom theme installed using Gnome tweaks. GTK3 iirc.
Modern Gnome applications using libadwaita instead of GTK3 or 4 will happily mostly ignore those, and the “User Themes” extension you need on modern Gnome to enable theming likes to cause problems. Usually one of the first “recommendations” you’ll hear when Gnome starts misbehaving is to disable your themes as Gnome just does not want to have them. I was just straight-up told to “not use Extensions if you want a stable system” (after losing about 40 minutes of work, again).
