Not necessarily. For autocompletion, for example, you probably only want
the public stuff. That's why I'm inclined to suggest the existing functions
should continue to only report advertised attributes, with a separate
introspection API that tries harder to find all accessible attributes
(potentially including those from the metaclass). That way users can choose
the one most appropriate to their use case, as well as being able to use
the latter to help test custom dir support.

Cheers,
Nick.
