This is a bit simpler but reminds me of the TC flower capability
discussion. Expressing features and capabilities gets messy quickly.
I have a gut feeling that a good starting point would be defining and
building a test suite or a set of probing tests to check things work at
system level (incl. redirects to different ports etc.) I think having
a concrete set of litmus tests that confirm the meaning of a given
feature/capability would go a long way in making people more comfortable
with accepting any form of BPF driver capability. And serious BPF
projects already do probing so it's just centralizing this in the
That's my two cents.
