Thank you Jeremy for this information (I had an intuition that it might be the case, but wasn't sure).
Re. Tim's proposal, an idea could be to have a packaged called "libgdm" that would contain all the binary files (including executable), and a package calle "gdm" that would only contain the configuration scripts that (propose to) install gdm as the default session manager (and the latter would obviously depends on the former).
Pros: would provide a better user experience for people installing gnome-shell (or other libdgm-depending packages)
Cons: it is a bit of a hack (and might even be forbidden by the debian/ubuntu package-naming policiy??...)
