stretch aux belt

[Poodle]

If you removed both the tensioners the belt wouldn't be able to take the correct route anyway, you would need a different length and it probably wouldn't have enough wrap around the alternator or power steering pump to actually provide useful drive. This is assuming you don't have aircon, as it wouldn't work at all if you've got all three drive pulleys in place. Bear in mind it also means a new belt every time you disturb it - no whipping the belt off to check for play in bearings. Finally, they're a bastard to fit compared to the standard one, so i'm struggling to see why you'd want to tbh.
