I could even see someone airdodge suiciding just so another player can't make it back to the stage. If teammates can use the move together, I can see even more strategy (launching teammates into the air, saving them from doom while you still have your second jump and up-B to recover back to the stage, etc.
You just reminded me of the cutscene in Super Smash Bros. Melee's Peach's Castle in Adventure mode, where Mario jumps to the fray, only to get trounced by Luigi.
