I don't think that either Jepp or NACO has the authority to do modify an approach plate.

They don't have the authority to modify an approach =procedure=.
However, they can chart the procedure any way they want. Overprinting
the words "Probably OTS, check notams", while raising questions that
probably should be raised, would be within their authority.
