Once the mindset changes and you stop using dead end switch loops the problem goes away. It is just something we lost from the tool box. We will end up with fewer of those cluttered ceiling boxes with wires going everywhere and that could make a lot of AFCI problems go away. (maybe an unstated goal) If you really need a 3 way switch loop, you can still use 2+2 cable, reidentifying the red tracer lead to an ungrounded color.
Unfortunately if this is on the lamp end of the 3 way loop, we have met the code but we may not have met the objective.
