I’d suggest as it’s not a layout displayed in any VW publication that configuration does not have approval as it causes obvious issues with egress and passenger safety, doesn’t represent the seating shown on the V5 and therefore would invalidate insurance coverage.That's not what I asked though is it?
Raising a concern that it may not be within type approval is one thing and helpful as others may not have considered that and then do the research (or take the risk, which they are perfectly entitled to do)
Stating categorically that it isn't but not providing a reference is not helpful to the discussion, it just adds to the confusion.
If you don't have a reference I suggest you edit your post to clarify that it's your opinion to save future confusion.
Feel free to submit the vehicle for SVA with that configuration and submit images of the layout to insurance underwriters to verify if they’ll provide cover.
I’d suggest that posts suggesting this layout are accompanied with a disclaimer that it is not an approved layout by VW, doesn’t reflect the V5 and will potentially invalidate insurance coverage.!
