I remember on the old forums that this was discussed but I think it basically was thrown out of favour as at the time since supports were the only ones buying pretty much the only wards throughout all stages of the game, it would compell players to wander needlessly through the jungle with the elixir which would reveal green wards instead of contributing to teamfights, etc, even MORE than people expected to do this formerly.
However, with the new trinket system and the elixir no longer existing, I'm rather tempted to say this could be a thing.
Take the red trinket, for example. Do you outright get rid of the ward, or do you intentionally leave it with a trivial amount of time left so that the enemy thinks they are safe, doesn't pay attention when it expires much sooner than they thought it would, and set up a gank based on that?
This could add a depth of strategy not normally looked at by the average player.
