"Remain outside controlled airspace" is not a piece of irelevant advice but an instruction to do just that. The reason why controllers feel obliged to say this is because when pilots have accidentally infringed controlled airspace that have inevitably said - " well we weren't TOLD to remain OCAS"!!!
As for the rest of your post - Kiltie -couldn't agree more with your response.
And "ready in turn " - why not just "ready"? I decide the dep order, depending on routes/slots/sector restrictions which crews will not know about/various other reasons that are not apparant to the the flight deck.
