Yes I found this with any use of a VR headset. I'm surprised not more is made of it - the neck is a very delicate structure, and surely any serious health and safety implications would cause all sorts of legal bother if nothing else.
It is absolutely a big deal. Poor ergonomics in regular office environments leads to neck problems that can get extremely severe. Throwing 2-3 more pounds on your head can make that a lot worse.
