I'm under no allusion that a /64 is going to be optional - it's really 
too late which is sad.  I think people have just latched onto it and now 
accept it and defend it without thinking about "is this still the 
answer?".   Just because it's in an RFC doesn't mean it's still the 
right answer in a changing world.

Yep - that's what I'm hoping (as I've said and clarified).   But I think 
the reality is that in the provider world, no matter what people here 
say, customer demand for an unchanging IPv6 range will increase not 
decrease - driving up provider routing size and complexity.
