Yeah, this is a valid point, but I think this would have caused
breakage only after d26a810eb which is a recent change. If that is
right, then I am not sure such an assumption is safe. Also, we have
already backpatched the probes.d change, so it seems reasonable to
make this change and keep the bool definition consistent in code.
OTOH, I think there is no harm in making this change for HEAD and if
later we face any complaint, we can backpatch it.
