You're correct, but observably that's not where the political trenches are dug. The wedge issues for the past few years haven't been around "how do we best implement the science", instead they're around fundamental disagreements that the science even exists.
Moving the trenches such that the main problem was trying to decide what the implementation of the shared science-based policy should be would be such a seismic shift in political discourse that I don't think I can visualise what that world would actually look like.
