And if we have to segment in such a fashion, the request and allocation of additional resources is a natural consequence of such containment.
There are other ways around such problems. You've got larger issues if
you need to worry about this.
fwiw, I'm (in the ARIN region) assigning the value of a /56 for each
CP(E). Along side of that, I'm ensuring that the encompassing /48 is
reserved in the event that things go that way.
This ensures that each client receives a /56 minimum, but also ensures
that I can assign the rest of the /48 if ARIN enforces it, or divvy it
up appropriately from the PE to the CE in the event </48 becomes standard.
