In which case do users have to ‘rm -rf ~/.cache/guix/substitute’?

That directory is only used by ‘guix weather’.  In that case,
‘--clear-cache’ could be added to ‘guix weather’ maybe?

Now, ideally there would not be any cache-related option because the
cache would always be valid.  If it’s not, it would be nice to see how
that can be improved or mitigated.

Thoughts?
