Yes, that is true, but there is no xdm package per se (not referring to the 
display manager XDM, but the init script xdm).
This is one of the reasons for the refactoring, because there is no single
provider for xdm, parts of the scripts are present in sysvinit, xinit, xorg-server.
And the overloading of terms for xdm init script and XDM display manager
.
This puts them together into one package, while renaming and clearing the confusion.

A potential check could be for xorg-server, which should be OK, but I 
don't see the harm in being a bit more cautious and letting everyone read 
it.

If you ignore this news item and upgrade your packages without installing
display-manager-init, you will no longer have an 'xdm' init script and you will
not get a gui on boot.

(Don't ignore news items people :P)
