I think we want something slighly less than this; rpm should track the
fact that a directory was created just because some files needed to be
put there, and it should be able to clean up if the last such file is
removed. But I should not fully assign ownership of the directory to
packages that just drop files in there. Ref-counting of implicitly
owned directories of some sort.

That assumes all directory permissions are created equal, which isn't
the case. Explicit automatic rpm directory ownership (à la rpm5.org,
with the associated metadata growth),

AFAIK rpm5.org generates the directory dependencies at runtime from data already present in headers, ie the case b) I described here: https://www.redhat.com/archives/fedora-devel-list/2009-June/msg00671.html. There's no associated metadata growth with that option, it's easy to add and forces directory ownership to be sorted out in the packages, otherwise the packages are simply uninstallable.

The directory information is of course in repodata too, but in the costly filelists part. Smart and apt have to download it anyway so they could be taught to look at directories with little zero extra cost, yum is the one that would take an extra hit here by having to always download filelists unlike now. Or move the directories into the primary metadata piece, or do a second depsolve + download round after ts.check() to pull in the runtime dependencies. In any case, every depsolver needs some modifications to work smoothly with this option.
