I think the simplest answer is: it's up to individual identity
providers to decide what is equivalent by setting up the appropriate
redirects.  I'm not sure we can standardize on rules that everyone can
afford to follow.  The redirection process can canonicalize any URL in
whatever way is appropriate for the identity provider that manages
that URL space.
