Right. Also of course we should follow the correct architectural
principle (that any prefix length is valid) but also the agreed
practical position (that the subnet length is normally /64,
as discussed in draft-ietf-6man-why64 that was just approved).

Now, we know prefix management should be at least categoried into prefix assignment and prefix distribution. :) Thanks for your participation in this discussion.

>> But getting back to where we start the discussion, I still think in a large network, the requesting prefix may not always be /64. It is reasonable to have multiple distributed sources for prefix assignment, in a large network. Autonomic network use case also includes to manage the prefix resource among these prefix pools.

But prefix _assignment_ will always be a single /64.   I suspect that this is the core of our miscommunication--if you talk about prefix assignment and prefix distribution as if they are the same thing, which is what we started out doing, then it's easy to imagine that we are talking about the same thing when really one of is talking about assignment (me) and the other about distribution (you).  Sorry about that.
