Generally, its prohibited to alter the altitudes/waypoints on an Instrument Approach within a FMS. Sometimes the altitudes on a STAR are altered from an At/Above to a hard altitude. Purely as a matter of technique, and depending on airframe and the company operations manual et, etc. (as I’m sure you know)
The technology has been around for a while, depending on the hardware. I agree with the razor blade euphemism. It’ll end in tears.
