It makes a huge differnce.

With the latter the /48's will be from a range we expect /48's
from (hopefully). With the former it's from a range we'd rather
not have to leave open to /48's. Slightly classful can be useful.

For their use it is no difference but from my view it is a huge
risk - potentially anyone can easily have accepted a more specific
for me or something important to me. I'd rather we all didn't have
to accept that, thus people are more likely to have reasonable
deagg filters. Some will just deagg crazily too given the chance
made possible by people like CloudFlare.

Keep a sensible deagg filter and CloudFlare may fix themselves
and not put anyone else at more risk.
