I agree (even though a couple caravels on auto-explore do the trick nicely), but it seems that they want to put a strong emphasis on exploration. This aspect of the game gets a whole SoPol Tree, new use with archeology, a new incentive with the world congress, maybe a new exploration unit (archeologist, exporer??), so it seems unprobable that they would add a way to explore the whole map without any effort really.
Agreed; also, reintroducing map trading would break the City-State 'find me X, Y or Z' quests and the Natural Wonder happiness boost (a bit like how if you discover Satellites without having explored the world properly, you get bombarded with Natural Wonder notifications and your happiness goes up by 3 or 4). A minor issue, perhaps, but something that does suggest it won't be making a comeback.
