Unfortunately the see and be seen environment has a lot of limitations - fundamentally on the performance of the Mark I eyeball, so having something that alerts you to most traffic is almost surely a net improvement. Of course having the technology cheap, light, and low power enough to be in the vast majority of aircraft would be better.
