Can it be that that script was not updated when we switched to systemd?

GDM fails to start at boot after removing LightDM
Status in lightdm package in Ubuntu:
Confirmed
Bug description:
I removed LightDM on the 14th and then didn't reboot until after
upgrading to Focal. The next reboot didn't launch a display manager at
all, and we tracked this down to /etc/systemd/system/display-
manager.service still pointing to lightdm.service. This is probably a
bug in lightdm {pre,post}rm?

[Touch-packages] [Bug 1860770] Re: GDM fails to start at boot after removing LightDM
debian/lightdm.prerm quite obviously attempts to remove itself from the
display manager set.
Also, “remove this non-default package and your system stops booting¹”
is a terrible experience.
¹: from an end-user perspective, booting to a black screen is the same
as not booting.

Can you point at some spot in the documentation where the behavior you
claim is correct has been documented? (If not, this may be considered a
feature request - importance "wishlist".)

I do not recall, but uninstalling lightdm should have done this
automatically.

Did you forget to make gdm the default DM?
sudo dpkg-reconfigure gdm3
If you did, this does not sound as a bug to me.
