There's a reason why the frequency is exactly 50hz or 60hz, and it's not "at least 50hz or 60hz". You can't just have 55hz on the grid, you'll destroy half a country.
That's why I say low frequency is problem, but high is not as much.
I don't think you said why?
It's not just about frequency - though that is important for devices that synchronize using the grid. When your frequency is going up because of too much power so will voltage. Think about that for a minute.
Not necessarily(see field windings), but higher voltage is indeed a problem
Not everything on the grid is a motor. Even if it was you would still need to rebuild the motor to change field windings.
some clocks are bound to grid frequency. It's the easiest most accessible way to clock time semi accurately.
