It's not as configurable as the distlib.resources cache (needs a method
to be overridden, which isn't ideal), but I'll look at making it follow the

No - currently it's created on module import by a line 'cache = Cache()'.
This can easily be changed to defer the cache creation until it's needed,
allowing user code to set a custom Cache. When I do this, no .distlib
directory will be created in %LOCALAPPDATA% unless no other
cache has been set, and it's needed.

I hope that answers things! I will update distlib's cache usage logic shortly
to (a) allow better control over the wheel mount cache location and (b)
create caches on demand rather than on module import.
