Please don't dismiss my statements as baseless. The presence of an issue does not imply progress. Jeremy is asking for a theming API or a method to let apps use a different theme besides Adwaita.
> Jeremy: I'm curious if you think there is a best way to have GNOME core apps continue to use our own theme.
> Clasen: If you ask me, the answer is no. To the best of my understanding, linking to libadwaita is an explicit decision to use the Adwaita theme.
I don't think there's any confusion or baseless assumption on my end.

Doesn't look like a community project to me, not in the least. It's as much a community project as Android (AOSP) is.

And GNOME/GTK devs get to decide what's the best possible experience for the user — removing any customization possibilities for the sake of consistency. If anyone doesn't like that, they can piss off. This is pretty much what "making someone conform to someone's way" looks like.
