While it does use /56 as an example (mainly because most of the
operators I have spoken to say that is as big as they'll go and many
are shooting for less) but it does NOT make that a recommendation,
from the BCOP:

"This is an example for demonstrative purposes only. Individual
operators will need to determine their own prefix size preference for
serving customers (internal or external). The SMEs of this BCOP highly
recommend a /48 for any site that requires more than one subnet and
that a site be defined as an individual customer in residential
networks."

Agreed, they must be considered.
