Actually, I have.  (Maybe I shouldn't admit this. :))

In a previous job, two security settings in gdm were changed from the defaults:
  DisallowTCP=false
  NeverPlaceCookiesOnNFS=false
These are "less" secure settings.

It was a large environment and the end users were used to logging to remote machines and setting $DISPLAY to run remote graphical programs. The default of 'DisallowTCP=true' broke that, so it was changed. And home dirs were all on NFS, hence the second change. Efforts were underway to migrate to ssh, but changing these settings minimized the pain during the transition.

The point is: had I not been looking through gdm.conf at all the various settings, I wouldn't have known about these two (until the end users started complaining).

Back to the anaconda issue: if the default is to remain MD5, then exposing the options in the GUI would give people the chance to make their environment /more/ secure in ways they might not have known about otherwise, so keeping it in the GUI seems like a good thing to me.
