I like this as well, I'm not convinced that any of mark's problems won't
show up in v6 networks though, even if the mandate (and hardware/software
fixes the mandate) is /64 only... people do dumb things, we can't really
stop them.

I don't see how the proposed wording makes this more complicated, for MOST
things people will just pick the default /64 and never look back (because
their upstream will be doing SLAAC and they won't even really 'pick').

For cases where people need (or feel the need) another prefix length
'RECOMMENDED'  means they can, they are adults, they can (and will) do what
they want.
