GOW has flatpak figured out, I generally do not like to give containers perms.
I am open to advice here

We got steam implemented (you can just run
steamfrom the console of any container regardless of host permissions) and through that tried flatpak, but it heavily leverages FUSE and it is not something we can do in userspace. In general we want to only ever have a user mount a GPU into the images. Flatpak will likely never be supported in webtop and proot-apps has expanded to have nvidia support now so that gap is closed.
