To Neverff:

You still have the option to buy that sweeper/pink to know if key locations are warded so if you want to set up a trap into a bush you have the option of sweeping it. Oracles lens also lets you sweep quite large areas ensuring they have no vision of you. With the earlier CV version however there would have been no way of knowing if the enemy team had vision of you. Also if you use your sweeper randomly say in a bush and there are no wards you still have the information that they don't have vision of the scanned area.
