I've been assured by a scrutineer that it is "recommended" so you cannot be failed on it. However, not all scrutineers may realise that, he only learned it at an MSA forum in Taunton last week so it may be slow to promulgate amongst all scrutes.
HOWEVER....
My understanding is that given the HANS is designed to work in that range of belt angles, one would be particularly stupid to do other than convert the car to comply. Too shallow an angle and the belt will slip off the device, too steep and it is likely to break your shoulder even in an accident where the FHR is not designed to work. It's like fitting a seat and only using pop rivets to hold it in place. you wouldn't do it because the consequences of doing it wrong are more dangerous than the consequences of not doing it.
