Again, I suspect part of the dichotomy stems from the IR being considered a "professional" rating in Euro land whereas in FAA IR land it is a rating for everyone.
This means the powerful professional lobby has a significant part to play in the dialogue.
It is bizarre really because light GA mixes no more or less with CAT whatever the flight conditions. It is equally bizarre given that most CP were once in charge of rubber bands. Perhaps as soon as they have an ATPL they forget their roots.
