If ops work that'd be simplest. I was worried that the exact limit
may need to be established at runtime based on FW/HW gen, and that's
why you place it here. But that's a more general problem with the
current simplistic approach of sticking all the capabilities into ops.
If you only need a static cofing we can go with ops and add runtime
corrections for all caps later on.
