I mostly agree, I've seen some SC animations and they must be very nauseating in VR. Here, I am just talking about making it clear to the player what happens, by showing that your avatar enters an out of body experience through attaching a HMD to his/hers face. It could be a very sleek looking device and it would explain well to new players why they suddenly are someplace else but really are not.
Edit:
It would also be possible to see which players are controlling something else when multicrew arrives by looking at their avatar. -Ah, my co-pilot is wearing a HMD, he/she must be controlling a turret or a fighter!
I'm pretty sure SC players have asked for it, but there is no VR support in SC at this time - the detail level is simply too high. Not a regular on the SC forums, although I am a heavy backer (multiple medium and one large ships) so things may have changed on the SC-VR front.
Showing other players your view direction does take a bit of added data (could be compressed, and doesn't have to be real-time like your own VR tracking - it can be a second behind and far less updates than your own head. Smooth inbetween and suddenly you'd be able to see where they're looking.
I am always disappointed when the ED avatar doesn't move with you/your head. In Eve Valkyrie, if you look around, over the side etc, your body gets pulled around too and it looks much more natural. And your collar doesn't come into view if you slump in your seat etc.
A good pilot avatar animation rig is a much needed VR-immersion feature. Not the bolted-in, missing texture model we have now.
