It's what I meant by that category. For now, any distribution shipping
only Mutter is targeting specific hardware.

I don't have any real objection to a separate gnome-wm-data package,
other than trying to avoid the extra work :-)

I talked briefly to Thomas about this on IRC and he was OK with the idea
of a gnome-wm-data package for GNOME 2.28, so let's proceed along those
lines.

Concrete steps I think are:

 - Review Jon and Vincent's patches again, ignoring the parts that
   touch stuff that should be in gnome-wm-data. I'll work on this
   today.

 - Someone does a new version of the changes removing the gnome-wm-data
   parts.

That gets us to a Mutter that can be installed and packaged.

 - Someone creates a gnome-wm-data package (probably by running
   git-filter-branch on Metacity to preserve history of the data
   files.)

 - Metacity grows a dependency on gnome-wm-data, and the moved data
   is removed from Metacity

These don't have to happen immediately, but would be good to get done
pretty early in the GNOME-2.28 cycle so that any issues can be sorted
out.
