Maybe, but each fix potentially fixes many other tests. Since each fix should have a normal regression test, you'd need to also build the profcheck variant to find what else got fixed.

Doing it periodically is simpler, and long term we don't have this list, meaning how we maintain it is for the interim. Unless I'm missing smth.
