The point being that as long maxCacheDuration hasn't elapsed it
wouldn't parse a metadata file even if the file had a fresh mtime?

I suppose that's what caching means, to some degree.

I guess I had imagined something where it wouldn't parse anything
that's not changed (say, $now - $mtime is less than a very high
maxCacheDuration value) but would parse something where $now - mtime
is greater than (a potentially very low) minCacheDuration.
