Sure, needrestart works for Debian. It's not always installed,
though. You could make it a dependency -- and now GNOME depends
on a non-GNOME package. The integration will be different for
each distribution. 

The GNOME people don't care. If you want this to happen in Debian,
you need the Debian people packaging GNOME to care about it.
