There was supposed to be a 'should' in there, apologies.
I've already clarified that VLAN/VRF is Good Enough for flow telemetry,
and that most who separate it out from customer traffic do so logically.
There are a few very large networks who do this completely physically
out-of-band; they made the decision that they were going to invest in
the ability to ship telemetry around and analyze it, and spent a lot of
capex and opex to be able to do just that.
