Should be harder to delete important branches
See e.g. https://gitlab.gnome.org/GNOME/gnome-calendar/branches
There are delete buttons for important release branches like gnome-3-28, gnome-3-26, etc. Seems quite easy to accidentally delete an important branch by misclicking. This should not be possible. There's also a big "Delete merged branches" button, which I assume might have non-fun consequences to the gnome-* release branches.
Can we disable deletion from the web UI for our release branches? (gnome-, glib-, gtk-*). It might be easiest to just disable branch deletion from the web UI altogether....
