I agree with D9009 as far as I recall going many years back when LVOps first were set out the procedure was commenced in order to protect the runway and landing aids etc for CAT 11/111. Nothing was done to dictate that CAT 1 was not permitted it was up to the crew to apply their minima for that. It just meant that if CAT 11 or 111 were undertaken then the safeguards for those approaches were in place.
