I suspect it might be something that has been left out in the rebase to 
GDM 3.28.1 - an earlier change log for GDM has:

* Thu Jun 25 2015 Ray Strode <rstrode at redhat.com> 3.14.2-4
- Make sure user customizations to gdm via /etc/dconf/db/gdm.d
   continue to work following rebase.
   Related: #1174564

So, I'm guessing that something similar was left out with this change 
from 3.26 to 3.28 ?

Maybe a bug report to https://bugzilla.redhat.com is needed ?

On a side note, I've now spent a day and a half trying to recover my
wrecked desktop profiles, with only a partial success. As it looks now,
I'll probably move all my desktop installations to openSUSE Leap 15 and
KDE 5 in the near future.

As far as I can tell, rebasing GNOME in the middle of a minor update was
not a good idea.

Cheers,

Niki

They did a similar thing with NetworkManager few releases ago that 
caused all my servers to start grabbing randomized IPv6 addresses 
instead of static they previously grabbed.

I don't understand why Red Hat makes these kind of changes in point 
releases - yet they won't update OpenSSL or PHP or Postfix in a point 
release.

It's like they use /dev/random to determibe where they require API 
stability between point releases.
