    I don't always have a witness when checking rotation but I don't think it is overkill.
    Hmm!

    Can you reverse the rotation of a VFD enabled motor by swapping any two conductors at the motor leads?

    Load side of VFD, yes. Line side, no.

    Then no.
    That usually goes into a plain diode rectifier which doesn't care about phase rotation.

    What if the VFD is interfaced with a shaft position sensor or encoder?
