No... It's action based. You can send it a different route, you can
replicate it, you can drop it, you can mutate it... You can send it to a
different destination for stateful filtering when it doesn't match an
expected pattern!

SDN is not just QoS routing, please stop saying that.

Anyway, prioritization needs more, not less,

Nope, not true. Had 1000 routes, only 100 available in FIB. So you filter
to the top 50 doing traffic and default route the rest of the traffic. Less
entries.
