I dont know if Jeremy Crawford ever commented on it. But hes also contradicted himself in the past on some things so I tend to be hesitant to see things that he says as gospel. Reason why is off topic so il hide that in spoilers.

Mind you my vieuw on his opinions are abit soured. I have had a player try to circumvent a ruling I did by suddenly looking him up mid session and commenting that Crawford ruled something else. And like, good for him. The anwser is still no. The fact that someone on the internet vieuwed something the same way you do now does not mean that im going to allow your little munchkin behaviour... Looking back he probably knew what Crawford ruled before suggesting his little broken move which just made the situation all the more shittier.

Also cant think of which case it was but on some cases he has said somethings work like situation A in 1 question. And later on when asked an almost identical question he said it works like siuation B. And this isent a dig at the man. If someone asks me questions based on opinion they will get different anwsers on different days as well. But when someones words are used as gospel about how the rules should work, I want there to be some consistancy in there...
