| At some point in the future when sources.g.o is redone, there | will be a sub-page for retired repos. https://bugs.gentoo.org/show_bug.cgi?id=196025#c33
FYI. Not gonna happen with the current setup.
sources.g.o is on life support anyway. For the git browser, we can easily mark repositories with a description or category denoting their status on request.
