I would not be surprised if they did not extend this to any active component of a commercial luminaire. The LEDs may last longer than ballasts but they are likely to still be replaced hot.
This is where I would rather see NEMA step up and come up with a standard connector for ballasts or any other follow on technology.
I am not sure why it couldn't just be the good old 5-15, 6-15 and 7-15. Then you are voltage identifying and standard.
