These will not get meaningfull strobes ever . I know that the majority here would try to get drones to behave like the other air traffic but the reality is that this would be impossible for the large majority of them . What i suggest is to find where the drone size becomes benign for aircraft and steer the manufacturers there so that when an iresponsable flyes one near an airport would be a 300g bumblebee , not a 5 kg beast. Also getting that iresponsable in jail would help more than trying to uninvent them .
