You cannot convince me otherwise. It is about being formally correct. Value 3 is an off-spec value that happens not to crash windows, and seems to behave like gray=0 . You cannot suddenly decide that 3 is the preferred value while zero is the fallback. Did you not read the opentype spec? The older truetype reference manual at the apple web site says the same thing. You can introduce orange / purple / beige compensation INTERNALLY, but you cannot suddenly decide 3 is gray and zero is something else than happens to behaves like 3.
