They're the same in game. It's consistent. Why is one different than the other? Instant is instant. If 2 things are performed instantly that should not be possible, what separates one from the other? Neither is possible in real life. You have to suspend disbelief in either circumstance.
The problem, one of them anyway, with this line of reasoning is that it won't be long before other aspects of the game are simplified for us, too. How long before we just have a button press to land our ships on planetary surfaces a la' NMS, for instance? This design decision is being floated to pander to the casuals, and it's the opposite of what I hold dear about ED in the first place.
