I've heard shooters in VR make people sick. I've also heard that one solution to this is to move people around by warping the player around the game field but this solution has always seemed odd to me. That said, that does seem like the VR "solution" to the problem and Doom VFR seems to employ that mechanism to make the game work. In service of the new play controls in VR the story is a bit different and given what you need to do that to make a VR shooter amazing the story seems natural enough to fit how Doom should feel. But with VR you sort of have to try it to have it all make sense.
