This is a sort of RFC in that I think it's probably best for meta-selinux to use this mechanism to keep from having to rename bbappends everytime something in oe-core changes. I guess the right way to implement this is to change the bbappends in meta-selinux when the version numbers change upstream.

It's a change I'd been advocating for quite some time now.  (Actually,
it was something I was somewhat surprised wasn't possible when I first
came to bitbake in general, so at least to me this change seems pretty
sensible.)

The risks you outline are real, but historically this hasn't shown
itself to be a significant problem so far.  The types of things this'll
hit on are characterized well in Phil's RFC set.  Stuff like sudo and
libcgroup which require bbappends but the contents haven't had any
meaningful change since the stone age.  :-)

I think this is actually a win for meta-selinux in terms of reducing the
number of commits like f0adb425.

I've already staged the proposed change in my tree and it seems happy,
so I'm inclined to merge it, FWIW.
