Remember, versioning rules are like D&D. The purpose of the rules is to give you a framework to operate in that is easily understood in the vast majority of situations, not to comprehensively define every aspect. You don't get any rewards for following the rules, after all. When things get weird, you just ask the DM, they make a ruling, and then you keep the game moving forward.

There's always going to be corner cases. Fortunately, there is always a person available to act as a referee.
