Is it something that Release Team should be handling?
I don't know. Do all devs have permission to create global milestones? If not, we surely don't either: release team doesn't have any special permissions on GitLab.
I think we have consensus that the next release will be GNOME 40 rather than GNOME 3.40, though. @ebassi, was this proposed to desktop-devel@ and is it finalized?
