What about daemons which drop privileges on their own? Shouldn't we
provide a directive to set the directory owner/group?
If this scheme is not flexible enough to cover the vast majority of
all cases (for services), then I fear we'd end up half of the services
using RuntimeDirectory, the other half a tmpfile. And that imho would
be even more confusing.
