It's a log scale - unless they add up to several times of the mainworld, I dont think it'll change the WTN at all.
Or you have reasons related to plot, your universe or maximum game fun, of course.
Or it’s a system-level designation with the main world as the ’Name’ of the system, in which case everything is just lumped together to create the trade codes, which actually makes the most sense.
