There is no rule that says you have to filter at /24, or that no other
network may ever advertise something longer. This issue is probably best
expressed as "you are highly unlikely to have full global Internet
reachability if you announce something longer than a /24", not "you are
highly unlikely to have anyone accept your announcement if it are longer
than a /24".

Just to clarify it was a /32 for Cogent A/B peering. When I set it up they didn't recommend setting no-export.
