The page was only changed yesterday, and I must say that the information on the FESCo policy docs does not reflect the info that this page had. It had a list of the third party repositories there etc.

(I did look for existing bug reports in Bugzilla, but I couldn’t work out how to see open bugs for GNOME Software in Fedora, and I don’t think I have an account. …And I forgot that Pagure also exists.)
