To design them not to regard unbeaconed walkers or cyclists as urgently as those with beacons would be inhumane and unethical, in my opinion. Both types of objects need to be processed at the state of the art.

But, just based on physics an AV will be able to locate and track a person carrying an RF beacon (well-designed) very precisely and consistently, as well as for an equipped connected vehicle. A person without one can be detected but not with as much consistency and precision, even at the state of the art technology and processing.
