I support the proposed change. More unit vision range and especially T1 + T2 radar range is a good thing and should help reduce the absurd scout and t1 radar spam that we got so used to.
However, I can also see the argument about scouting being quite easy compared to other RTS games. Scout planes that can quickly fly over the map, are nearly impossible to intercept, and get full vision of an enemy's base or army are quite unique within the RTS community, and undoubtedly already very strong. So I would propose to exclude scout planes and some other high-visibility units (cruisers) from this change.
