2 out of 2 large backbone networks I've experience with use inband for flow export.
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.
