Or just leave an unexplored area in your current world for the future.

Basically OP is asking if future updates would make that impossible to do as the world would not work anymore.

The last thing I want to hear from the devs is "we wanted to put this cool thing in but didn't since it could mess up peoples worlds" ... Especially being in Early Access the devs should feel no qualms about making big changes even if it destroys peoples worlds.
