I guess I've totally missed your point....Throwing my nickel in here from my point of view.
If I am open carrying and an officer asks if I have a permit I would prefer to assume that someone has contacted the officer with a concern that someone is carrying a firearm therefore making it within the scope of their job to ask. There is no way for me to know whether or not this is true so to produce a license when asked ensures that I comply with the law. It would be great if the officer were to come up and say something to the effect of "Jane Doe called me over to her vehicle concerned about your firearm, may I see your license?" But I doubt it's going to happen that way.
It's a catch 22 and I would rather be friendly and produce my license since the law isn't clear about asking part.
This tells me that as long as I produce the license when it is demanded I can not be restrained or disarmed and this part:
Basically tells me that if I am asked to produce my license if I am contacted during the course of official business I have to do so and I have to inform an officer who may be unaware of my carrying as soon as I am able to during official business involving me.
