no, you're not. i agree that the idea as it was originally intended no longer
makes much sense. but i think the underlying idea (i.e.that there should be
some way to indicate that changes have happened at a more finely-grained level
than the entire profile) is still a good one. i'd love to have some UI that
indicates what exactly changed within a profile from one version to the next,
so i can selectively choose which configuration to reapply, minimizing the
possbility of side effects.
and i want a pony.
+1 to the deprecation.
