As Joaquin always reminds (at least) me, there's a big difference  
between "identity" and "identifier". Actually, I think there are at  
least three different things:
  - 2 identifiers may or may not be the same
  - a relying party may or may not be able to tell that 2 different  
identifiers identify the same person
  - 2 different identifiers may or may not identify the same person  
(but no relying party may ever be able to tell)

I just added this case to the wiki.

I think this is something we may want to put on the roadmap ... but  
I'd argue let's finish a bit more of what's on our plate already  
before we get there ...

Just added a new section to the wiki:
