The cache should ideally be per source-registry entry;
and managed by the same entity that manages said entry.
Thus, I was thinking of an optional second form
in cl-source-registry.conf file.
Or a separate .cl-source-registry.cache file.

Yes, that's the general thing I'm thinking about:
kind of back to the concept of link farms of ASDF 1,
but only as an optimization, without any additional user configuration required,
and leaving system administration to system administrators.
