Why core aten IR doesn’t contain scalar_tensor overload version of some ops, like bitwise-like ops, remainder and so on?

Many ops has scalar_tensor version in native_functions.yaml, but are not included in core aten IR set. Some of them has same results between scalar_tensor version and scalar version like bitwise_and, but some are different like remainder and bitwise_shift. Is it missing or is there some other reason?
