It's not worth the complexity.  (On top of the SUID issue already
mentioned, there is also the question of cache invalidation.)  With
long-living processes, you could just read in the a designated list of
directories at startup and use that to seed an ephemeral cache.  Hence
my question about the directory layout.

It would work, it's just more difficult to use.
