I would argue that this is not a case for PPR, but a case for people to read the NOTAMs (and properly punishing those who don't).
There's no relation between the conditions of use for a particular a/d and the requirement (by law AND by common sense) to consult NOTAMS.
If anyone allows us to use their airfield then certainly they have a right to impose some conditions, and instead of grumbling we should be happy to comply, lest we loose one more airfield.
