Yeah, I've been talking to people on and off about this for over a
year. Even though providers can lie about their allocation
granularity, most won't, and the ones that lie would probably merit
total blocking anyway.
I'm less worried about those that lie outright than those that just
don't care either by not bothering to specify a policy at all (unless it
becomes mandatory somehow), or have more granularity than can be clearly
specified in a single policy.
For example, their policy might be to allocate at the /64 level, but
unless they also prohibit customers from obtaining more than one /64...
