+The trade-goods.plist was designed to make commodities simpler, but only made it more comprehensible. It didn't really let one do anything particularly different to Elite 84 markets - mostly including the "Rich Industrial -> Poor Agricultural" single spectrum. One can tweak that a bit with peak_export and peak_import to get slightly different shapes (so a commodity might peak at Poor Industrial rather than Rich Industrial) but it doesn't really give one the option of a third economy type still.
