https://www.gnome.org/getting-gnome/ has wrong details for current distro support
Debian has 3.38 according to https://packages.debian.org/stable/gnome/gnome-shell Gentoo has 41 according to https://packages.gentoo.org/packages/gnome-base/gnome-shell
Maybe the page could also include links to the package pages of the distributions so even if it's not always up-to-date the second the distros update then it's easy for users to check the upstream status. This came up on the extensions channel when discussing which versions might an extension developer want to support.
