Honestly, I think you're creating a problem that in reality does exist, The galaxy merely allows Shepard to pick a destination for the Ship to go and the Normandy does not go anywhere unless you specific choose to land on a certain world.
I'm not quite following this. I said I wanted to know the position of the ship, and that I want the position of the ship to be worth knowing. Are you saying I should just not want those things?
Though I suppose that the ship's indeterminate position in ME1 is a symptom rather than a cause.
As long as I'm talking about hypotheticals, I thought that the galaxy map was an incoherent mess in all three games. It's both a library computer and a navigation/scanning interface, but you can only look at the known data for a planet when the Normandy is orbiting it. (Or maybe just when you're in the system in ME1, depending on what you think is going on with the map.) We should be able to access that data without moving the ship,
