Well I am not sure, but maybe that is the way jorb and loftar want the world to be. With a different terrain generator it might be possible to create hidden spots without having to make an endless world with no trade whatsoever.
Those two sentences of course have implications on almost all important developments for the future. Map gen, fast travel, trade, town defense. So I say rather give the devs time to bring up something good and us being stuck with the old world for some more, than a mapreset now.
