Looking at the Market UI, it only has three slots for upgrades, and the other two are taken by Coinage/banking and guilds. I suppose they just chose to make cartography prerequisite, because it sorta, kinda makes sense (you can see the allied markets), but mostly just because they didn't have space. Of course it could also be to indirectly make caravan cost more.
