I disagree as well that there's a "majority" (or any sort of consensus) for A,
and it would in fact be my last choice of the four possibilities (counting 
implementation 
dependent).
 
I would prefer (in order):
C (flexible)
implementation dependent (what you suggest below)
B (strict)
A (flat)

        You could say that, but I believe B and C should be separate.
        Actually,
        
        - Francis (who supports B) said he said he'd rather prefer A to C,
          because C would introduce too much complexity.
        - Markku (or Dave? anyway who supports C) said he'd rather prefer A to
          B, because we'd not see much benefit to separate the field
          (i.e. 4+28) if we get rid of the flexibility that C provided.

        Yes, it would.

        Hmm, I guess it would be okay to leave it as implementation dependent,
        that is, "we adopt the flat 32 model, but the actual mapping from a
        particular zone to a zone ID (sin6_scope_id) is implementation
        dependent."  Does this make sense to you?
