There no offence Grumble. I was just asking to understand what modification could have caught your attention.
Your impression is a 100% correct, I could give you many examples on that. On another hand we have many rules that are funny, for example a car will fail its annual MOT if it is fitted with extra driving light or rear working light, yet you could easily fit them for the rest of the year without having any trouble with the cops. It has become a yearly activity to uninstall them before the MOT to re-install them an hour later.
