No, cache loader only scans which files are present in the cache
(and their sizes), it doesn't try to read them. Raw keys as
stored in cache file headers are only needed for a safety check to
make sure there are no MD5 collissions between different keys, and
this check only happens when returning an actual response from the
cache.
