Good point.

We do both - prefix list + AS_PATH filtering as well as 
origin validation.

At this point, you're likely to lose longer prefixes from 
customers if they forgot to ROA them, but the rationale is 
that if a customer has sufficient clue to ROA their 
aggregate, they can quickly ROA a de-aggregate or fix it in 
case they forgot.
