Exactly. That is why we avoid describing what happens when you set it on a case sensitive filesystem, to leave the door open for such a cleverness. It may still be a mistake in the manual that we did not explicitly say that setting core.ignorecase on a case sensitive system will give you an undefined behaviour.
