Similar to the realization that saying "no" is one of life's important skills to internalize. Closing off possible avenues of explanation is just as much of an advancement as finding evidence to support an explanation.
Physics took 2 wrong roads and it got stuck in a local minima of the truth plane. Understanding that physics is the most ignorant field of science and how proud the field is of it's models, I don't think this will come anytime soon.
PS: you need to understand how gravity is derived to manipulate it's propagation. Since the mechanisms are very stable due various reasons, only a very good understanding of many processes will allow you to design an experiment that works. I have adopted a very fringe physics model that is unified and explains more using less assumptions. From this perspective I can tell you that contemporary physics is so far from understanding, that most likely we will not see anything in this direction, before we fully trashed our planet.
