The use case was people wanting different menus on the panel vs. on the
launcher.  Or not appearing on the panel at all even if there wasn't a
launcher available.  So the specific case was with Tomboy where in the
menu on the panel they wanted to have a "Quit" button but the launcher
menu automatically has a close (through the WM) and they didn't want
both.  Also, in our specific case there are more restrictions on the
menus in the launcher (no submenus) so if an app wanted to use those
they wouldn't want it to appear in the launcher.

I would imagine that for most applications if they were going to use
this feature they would be building more than one Item.  They'd build
one for a very specific visual target and then another that is a generic
item for all other visualizations.
