Sending flowrecords to your slow ppc CPU just to allow export in non-HW
interface is silly, when HW can export it directly, without ever hitting
your control-plane.
Polling SNMP is low volume, so you easily allow RP to poll for them from
HW. But implementing this also in HW would be interesting for low-interval
SNMP polling, then it also would stop working in your non-HW interfaces.

Sure, if performance is not important and if you're too poor to buy
interface in your router.
