Yes, I absolutely love the /24 filtering "everybody" does. Internet littering at its best.
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.
