That is even worse from an ergonomic and practical perspective...
Better to have your VR environment calibrated with suitable space around it to comfortably relocate yourself than recalibrate the VR environment to an unnatural position.
As for strongly advising against something like what your proposing... it is all to do with ergonomics and ensuring your physical play space matches your VR space close enough to make it a safe, comfortable, and immersive experience.
When the VR calibration goes squirrelly and is offset in any given direction the experience can be extremely disorientating.
Unfortunately, my on-topic friendly tip for VR explorers you've turned into off-topic misinformation. I don't want to, but I need to correct some of what you say.
Firstly, this has nothing at all to do with calibration or re-calibration. I'm not sure why you keep saying this. Calibration/recalibration is a 5-10 minute step-by-step process that every VR user hopefully only needs to do once or twice. Personally I've done it twice so far in almost 12 months of use, once when I bought the rift, and a second time after I bought the touch controllers.
The tip I gave earlier is simply resetting your HMD view, which incidentally oculus calls "Reset View". This is app/game dependent. Every app/game developer has written their software to handle "Reset View" the way that works best for the app/game. For example ED calls it "Reset HMD Orientation" and maps it to the F12 key (I've also bound it to a Hotas button). Again, it has absolutely nothing whatsoever to do with calibration or recalibration of your VR system, and I hope new VR users don't get the wrong impression from your posts.
You mention ergonomics which also seems largely irrelevant. The simple tip I gave leaves you sitting (in the real world) in exactly the same position you always sit. You have exactly the same surrounding space to move around in as you did before. And if any VR user who purposely resets their view to a slightly different position can't reconcile that move with their real world surroundings, then I'd suggest that perhaps they're going to have a tough time in VR in general.
I do agree with you about immersion. I've already said this is a subjective thing. If people reset their view so that they're a little way forward and believe that's affecting immersion, for example they look down and see their body is a little further back than it should be, just revert... this tip wasn't for you.. press F12 and you're back. Personally, I prefer the better view.
My view on the "Reset View" function within any game is to experiment and have fun. It's particularly fun in ED. I could list far more examples than the innocuous little "forward view" explorer tip. For example...
To get double the cable length worth of "VR travel", move to a position (sideways and back) at the extent of your HMD cable, press F12 (you might have to get someone else to press it for you as you will be 4 metres away from your controls). Then you'll be able to move up to 8 metres in the opposite direction, in effect giving you close to 8 metres of travel from the pilot's chair. This assumes you have that much space to move in your real world

. This works well in the Anaconda ofc due to it's size. You can probably reach the co-pilot's chair!
