It matters.
In fact there's a certainty that they would let him know before they draft a QB in the early going. Not that he ok's it. But they show the man that respect for who he is by giving him a heads up that it's coming and hey you're still our dog and he's for the future and all that. Or they have the conversation before the draft and preload him on the possibility on the few they really like. Or both.
I think the casual dismissal of the QB feelings is unrealistic given that they just had to clear the room out to have McVay and Stafford agree on structure to make him feel, as Stafford put it and I paraphrase, that he was important to the team. There is zero chance they would make a move for a QB up high without telling him. And I think it is downright unlikely they would move up for a QB by using significant draft capital unless they are convinced that QB's value is so great that they are willing to accept pissing off the starter.
