This would be super useful on dark stages, because the player cannot see where the switches are.
I usually don’t play in full darkness, but that happened to me and it was a problem.
Actually, the only switch I don’t wanna see is the current scene: if I have to stomp on a switch, it’s surely on of the other scenes. So, even a “reverse” function would work, where all other scenes are lit and the current one is off.
Check the pic: it’s super hard to see where the switches are!
