If regulators can 'approve/authorise' some of the dross in the manuals that some airlines shove under their noses for a stamp, which are then later amended when the guys at the coal face realise that it doesn't work, do not be surprised that something so apparently perfunctory could be allowed. If the hand that feeds you asks for permission to do something and offers assurances that it will work, the the stamp will be warm and waiting. It happens with a whole host of issues that will alarm you.
But don't forget to dot every i and cross every t on all the duplicated everyday flight paperwork. With out them a near dangerous flight may occur.
