I must say I don't really understand why the consensus paper says that.
Call it "politics" or "power struggle" or whatever.
When EN ISO 14971:2012 came out there was a big outroar that never fully died out since. Initially there were a lot of fierce debates for and against (Elsmar holds some of that good stuff), but at some point there was nothing else left to say, and we got a little weary, and it seemed like the trench-lines have pretty much settled, so we started waiting for 1918 to come so we could all go home.
Anyway, the point is that there seem to have never been a broad agreement, and there still isn't, and everyone is just trying to get along somehow - not by means of clear rationales across the board, but more through negotiating agreement case-by-case (i.e. specific company and NB).
The "consensus paper" doesn't really represent a consensus. First, not all NBs subscribed to it. Second, it was never endorsed by any official arm of the EU (let alone the Commission).
If your NB subscribed to it / goes by it, good on you. If not, it'll at least give you some ammo, and some reassurance that you're not crazy or stupid, despite what your NB says.
