Agreed, but because the predicate tests the vector != NULL it is a
step away from the feature I need, which is to change the evaluation
of the preditcate at runtime.

Ok, I see that now.  How about adding a predicate vector to gdbarch
being the "Good incremental step"?

Are you describing the function predicate, or an all singing all
dancing single-step function (as I suggested as well).
