Useful anyway if you want to clean up before making a backup.

In terms of complexity, I think this is the best solution - there's something 
of a limit on the cache size, since how much can you download in a month, 
anyway? And for those fairly rare files that remain valid for years, that's a 
little extra downloading every now and then - though you could touch(1) them 
every time they would have been downloaded, to keep them fresh and in-cache.
