yea, skewed magnets are the standard outside rc. I have not seen it applied in rc motors however. But if we are wishing for better tech a sinusoidal waveform and field oriented control is the standard for cogging control outside rc.
I have also seen poles separated longitudinally on the rotor rather than side by side which does offer some control advantages.
I do know of experimentation with magnetic material that isn’t north or south but a continuous blend from north to south and back again. this means no big changes in fields that come from stacking north and south side by side.
