With the added benefit of neck strain!
And this would make it even worse.
The problem with physical displays isn't that you can't move them around, it's that there's no reason to.
It's like a chair, sitting for too long is terrible for your body. Chairs don't literally limit you from getting up, but there's just no immediate reason to get up, do some stretching.
It would be the same except you're adding annoying glass and plastic attached to your face.
If a headset can be light enough, it can be a tool for AR documentation overlays. It's like taping a manual up next to the thing you're working on.
For example, engine components. I've seen airline mechanics consulting laptops as they work on engines. I didn't get a close enough look to be sure, but it seemed like it was a combination of manuals and running diagnostics.

Some monitors come with swivel mounts to support both horizontal and vertical modes. It's common enough that I think it's worth exploring.

This is absolutely true. Getting headsets down toward the same weight range as regular glasses is probably a major hurdle for use outside industrial or piloting applications and into the office.
because putting weight on your head does that. Your muscles and joints are not going to like it no matter how you try to be comfortable.
