Some some sort of mapping of packages into sets space does seem
better than changing the behavior of these packages other cases.
However, PROPERTIES=set will still be useful for governing
recursion, since recursion into dependencies is probably not desired
for non-meta packages in the same sense that it might be desired for
meta-packages.
