I don't understand how mines would make a difference.

I mean, 1) boos take the place of mines in all cases, 2) if I hold a key down for too long, my keyboard starts to repeat the key (automatic mine), 3) mines were designed to force dancers to move their feet; how hard is it to move your fingers? And how long do you leave your finger on the key, anyway?

I suppose mines could be used for distraction, which can be a valid addition, but I'm simply not seeing anything else.
