The distinction I see is that while a planned flight may be classed as either VFR or IFR, by definition the only time it is “operating under Instrument Flight Rules” is from takeoff to landing.
It is axiomatic that the taxi phase of flight, up till now at least, is a visual procedure that does not rely on instruments for navigation.
You could say the same about a visual approach but that is an IFR procedure. Assuming that PEDs really can interfere with navigation, although you're not navigating on instruments while taxying, you do need your nav instruments to know where they are on the ground so that you can use them immediately after take-off.
