IMO:

someone writing the policy statement saying 

term { accept; } 

is enough to satisfy my concerns, it’s when people do nothing and are left sending their full rib back to their upstream causing load it’s a problem.  While we’ve moved past the days of 11.1&12.0 in IOS land where there was a high cost on the CPUs to x86 compute where the burden is less, it’s still additional processing and a resource consumer.
