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.
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.
Oh ok, I guess frequency maintenance on the grid isn’t a problem then and all the pumped storage and battery installations can shut and all the grid planners can go home and the spots markets can close and we can just dump as current as we see fit onto the grid and you’re right and I’m wrong.
By not all you mean motors with windings connected to grid? Well, they still will work on higher frequencies, but on higher speed. Real problem is low frequency, not high. Well, 0.5kHz not all devices can handle, but most consumers(even conumer electronics, no pun intended) even rated to 50-60Hz range. So 46-64Hz should be fine for them.
What about sensitive devices keeping patients alive in hospitals?
Sensetive devices that can’t handle range bigger than ±0.4Hz? Are you kiddding me? How does that even pass certification?
Most frequency-sencetive devices are not consumers, but transformers and turbines.
Usually too low frequency is issue, I can’t imagine why even double frequency can damage PSU.

That’s why I say low frequency is problem, but high is not as much.
I don’t think you said why?

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.
Ok, your particular device may handle a wide band of frequencies. Congrats.
But do we agree that not all devices can? What about sensitive devices keeping patients alive in hospitals?
Those would not be plugged straight into the grid but with a power conditioner inbetween

lol If you think hospitals don’t have managed power systems you shouldn’t be contributing.
Also lol if you think medical equipment isn’t required to be robust, have you ever read a supply tender spec for a hospital?

Transformers are very important for the grid though. You also have large synchronized motors connected to the grid.
