I don't remember if you need the yellow switch to advance in the game at some point?

You have to activate all the switches in order to access the Special World from Star Road 5. You'll see why here.

It also just makes the game easier in general to have the switches activated. They provide you with more blocks to walk on.

Makes sense to me.
