Hello. Sorry for the delay, I had apparently forgotten about this. I'm not sure I understand the reasoning here, but I'm not sure I understood the reasoning for the FalseLanesZero to begin with.

You can leave the existing tests as they were, and update them with the new codegen. They will either be correct and better, or else we need to look into what is going wrong with them.
