I think you need to do some trial and error, and was saying we should be scared of it ( / be careful about it / minimize it, though it’s subtle why minimization might help).
For example, suppose that I put a random 20 gate circuit in a black box and let you observe input-output behavior. At some point you don’t have any options other than guess and check, and no amount of cleverness about alignment could possibly avoid the need to sometimes use brute force.
