One is supposed to able to change properties after creation of the graphic, and since map_projection is a property, I would expect to be able to apply a map projection after creating of the graphic. Now, I can see that applying a map projection after the creating the graphic could
cause all sorts of problems, e.g., axes, honoring aspect ratio, etc., so probably the documentation should be updated. Maybe there is a way to handle things gracefully.

Well, there are a LOT of things about IDL that make me grumpy. I guess
you just get used to it. ;-)
