Comment 73 for bug 857651

I was made aware in bug #1667113 that this seems to be the root bug to dup this onto.
I know this comes down to accountsservice, as others not using it like sddm are just fine.

If we stick to depend on accountsservice, then it comes down to the following
$ dbus-send --print-reply=literal --system --dest=org.freedesktop.Accounts /org/freedesktop/Accounts org.freedesktop.Accounts.ListCachedUsers

Which should get some sort of the old hiddenShells feature back to exclude those users.

Could someone of the desktop Team give this a look from the 18.04/gnome-shell POV - will this go away?
