No, because you have no idea how long the majority of us complained about picking up SMGs with 3x and 8x scopes on them when looting before loadouts, not realizing, and then dying getting into fights when getting jumpped on cause suddenly our whole viewpoint was changed from 3rd to 1st person.
If this were a 1st person shooter and only a 1st person shooter I could agree that ADS and having a sight on your gun should force the scope, but its absolutely disorienting from 3rd person to 1st, especially when you don't know you have it and you are just reacting to the massive firefight around you if you jump immediately. If you want scope by default when you ADS then turn on the option in gameplay.
