Never say nobody. Methinks these rules adjustments were the result of a critical mass of rulings rising up the ranks until WotC noticed that so many people had to make the ruling. This made a straight-up rule necessary. It happens, and this one coincides with the clear original intention of the rule.
I doubt it. I suspect that they made a ruling like TSR did back in the day - because someone theorycrafted a question and they felt compelled to answer it. This was half the problem with the attitude around 2nd edition - "Sage Advice" in Dragon magazine. "Let's come up with stupid scenarios that nobody is actually going to do and then pretend like they're gamebreaking things and not things that the DM is just going to give you an evil eye over and say 'Thanks Derrick for pointing that out - you get a cookie for figuring out how to make a couple of rules interact to make something stupid out of them. Now never speak of it again because it's stupid and you know it.'"
This is the attitude that eventually led to 3e, where you needed everything codified like it was some kind of fantasy physics engine instead of a set of game rules. I was hoping that 5e would leave that attitude behind.
