Title basically sums it up. When using Creative mode there is no reason why the map shouldn't just be given to you. This would help with custom map making by eliminating the need to fly around for up to five minutes for large maps.
But then you wouldn't be able to make maps that are non-complete.For example,maybe you want to create a map that only shows the path to some area and nothing else.Maybe you don't want the map to show your super secret golden city or something like that?
This issue could be solved with a "Finish" button to complete the map or some other way of completing it manually.
