Consider a CE with 2 LAN interfaces, it hints a prefix length of /60.
The delegated prefix is /48. At renew the CE again hints at /60??

Or should be receipt of the /48 be considered a "configuration" of a
larger prefix?

Still thinking this should not be part of the requirement, it's
distracting from core intent of the requirement (which is to request a
sufficiently large prefix).
