This is mostly driven by academia, a bunch of universities
collaborating together. Minimal operator input which is a shame.

Yes that was the point I was trying to make too.

So an "easy" use case might be a BGP free P node for example; a low
touch config box with minimal features and less to go wrong. VPP is
pushing the 1Tbps mark on x86 hardware now. But 10x100Gbps Ethernet
NICs and 64 cores ain't cheaper than a whitebox device right now.

Cheers,
