Pop_OS! GTK theme for snaps and GTK theming

I really like how snaps work and the support by big companies in general. However the lack of theming is a big letdown. And what’s even more so is the lack of the pop theme in the gtk-common-themes snap. Pop_OS! is pretty big now there’s a large userbase. Sure it ships flatpak by default however flatpak is too sandboxed for me since I use a lot of SDKs and development tools (And probably a large chunk of Linux and more specifically Pop_OS! users). Snaps integrate with the system a lot better.

So I would like to know the current state of GTK theming support and maybe if possible add the pop theme to the gtk-common-themes snap.
