No Support. You can already build 2xn piston doors relatively easily using basic redstone (and I've recently learnt how to do 3x3 doors). There are some situations where you don't have the space to do so. However:
- In Survival, you don't need to build a door that big; just use a smaller piston door or a standard wooden/iron door.
- In Creative, just use commands.
Pirateboy responded to this and I think he was just off the mark, but I think the "Rocket-Powered Elytra flight" one is an appropriate example here.
But let's not even go that far. As you mentioned, a 2x1 piston door is possible with redstone. Therefore, why did Mojang add new door blocks? Why did they add concrete when there are a lot of different colored blocks including wool? Why did they add crafting tables in the first place for that matter when they could've just let the player craft 3x3 recipes in the inventory with practically no loss to gameplay? There are plenty of features in the game that could either be wrapped up into a far more simplistic feature or are completely pointless besides aesthetic value.
Also, are we going to screen all new features in the future just because either redstone or commands can replace them? This argument is almost as bad as the "If you want this feature, use a mod" argument. I'm not saying the redstone or command argument is never valid, but you can't judge every new feature by whether or not you can replace it with either. In addition to that, consider the fact that, as you said, redstone takes up massive amounts of space and it's incredibly difficult to hide it, especially in smaller builds.
If you're going to argue that a redstone equivalent invalidates the need for a suggested feature, at the very least the feature:
- Should have little to no aesthetic value
- Should be functionally equal to the redstone equivalent
- Should not save large amounts of space that would otherwise be filled by the redstone equivalent.
