I think 1X is a hip filter from the MTB world, where it is quite appropriate. Doing single track, there aren't many long, even climbs where one needs to fine tune the gear. What is needed instead is reliable instant shifting and 1X is perfect for that. For road cycling, I want my low gear-inches as close together as I can get them as my best climbing cadence range is small and gets smaller as I tire on long climbs.
