You have an interesting approach: more or less a wrapper function around the original API^h^h^hUI. It has the advantage of preserving the—presumably verified, and maybe even certified—safety protocols. This technique might have application in the healthcare field. We have already seen evidence [1] of diagnostic or therapeutic equipment going unpatched for years because the manufacturer disallows configuration changes after FDA certification for fear of triggering a recertification event. Besides adding convenience features, it might also be suitable for retrofitting safety features to existing, irreplaceable, but hazardous equipment [2]. A similar approach was used to control a toy Big Trak in BYTE years ago [3]. ——— [1] David Talbot. 'Computer Viruses are "Rampant" on medical Devices in Hospitals'.
