Well, you don't get user switching (and the kickoff item) every time
something's messed up with your PAM session. This is not exclusive to GDM
though, SDDM suffered from this a lot too in past. Changing something in
PAM, PAM configs or the DMs can bring the problem back.
Anyway I agree this should be tested.
