lol let's say they're less likely to impact correctness than an arbitrary new optimization.

If you find a bug, it's in the optimization passes (that don't reorder and should, if you decide to do this).

At this point this is like (usefully) fuzzing your optimizer, which long term is going to be great for correctness.
