I think enough do. The whole deal is/can be deciding who is in the middle because they can hit anyone, but can be hit by anyone. Do you put in a sweeper who can take out everything with a move like Eruption or Earthquake, or do you put a bulky support in the middle to cover your sides?
I've been creating a Moxie Earthquake sweeping machine for Triples. The center is a Krookodile (C.Blackeye) and the sides are Electabuzz (BROW) and, for now, Togekiss (Airplane!). On the first turn, Airplane! uses Tailwind, C.Blackeye uses Protect and BROW uses Magnet Rise, and on the second both Airplane! and BROW use Follow Me while C.Blackeye uses Earthquake; on the first turn it's usually not enough to OHKO anything, and he's not invested in defenses at all, so Follow Mes are important to protect him. Eviolite turns Electabuzz surprisingly bulky. After two turns of doing this, C.Blackeye will more than likely have KO'd some things and will have Moxie boosting his Attack, one stage per KO; a triple KO gives him 250% power just like that. No need for a Choice Scarf for Speed or a Choice Band for power: a Life Orb gives him a little extra boost while also allowing the use of Rock Slide or Crunch when it's a better option than Earthquake.
I was using a Whimsicott (Booty) to set up Tailwind with Prankster priority before the Togekiss, but his inability to learn Follow Me left one side free to attack C.Blackeye on that crucial second turn. But a Worry Seed, also prioritized by Prankster, means that he can disable Levitating opponents before C.Blackeye's Earthquake, while avoiding the Earthquake itself by way of an Air Balloon. He's still on the team and can contribute if one of the Follow Me users gets KO'd, usually Airplane!, because Airplane! is faster than BROW which means she takes attacks from the middle opponent when both use Follow Me. And she's less bulky and can't nullify her weaknesses like BROW can.
Initially, Aqua Jet and Ice Shard were of some concern, but Follow Me takes priority over those.
So this is just one thing, revolving entirely around making one ability as useful as possible, and I came up with it all on my own and I am a moron. Imagine what else you can do. Gastro Acid works on Slaking...
