I'm not very sure, I think there is basically no probability of using it because tools should need CPUID instead of predicate. Predicate does not exactly correspond to CPUID, for example we have predicate `NoAVX512`, `NoAVX` and `NoVLX_Or_NoVAES`. I am trying to remove these predicates b/c they affect the test coverage.
