I'm not sure if detector is any better than observer. Isn't it the issue of when does it collapse/decide (also problematic terms) rather than the multiple options propagating into the detector? Observer get used because at least then someone is experiencing the decision. Many worlds punts on that option by making a new observer world each way. I'm a layperson who reads a bit so I could be misinterpreting. I was always partial to the idea of probabilistic squeezing rather than collapse. In the absence of quantum gravity, probabilities can propagate only as far as their gravitational effects allow. As particles interact the compatible possible positions reduces to eventually squeeze the location to an infinitesimal size. It may be utterly wrong as an idea but it would negate the need for observers, detectors, or many worlds which makes it a bit compelling.
