As this (switch from GDM) has been discussed for releases, I don't know
what is it why the switch shouldn't be made.

I do wholeheartedly think we should switch, since there is not any
bug/lack of feature that is a showstopper. Natty is not LTS, and even if
LightDM did break in a way or another, it's still okay. Things happen.
At least we got testing from a broad audience.

Those who want to edit their login screen, can probably edit a text
file. If not, they probably shouldn't tweak the settings anyway.
