Hoard does much more than it's name implies. Essentially hoard doesn't
just make sure we refetch files that have been updated on the server, it
is also very closely tied into the cache replacement algorithm.

I think this revalidation happens either way, because the hoard walk
also happens when there is no active hoard profile, it recalculates the
dynamic priority which is used for cache replacement decisions.
