If you do the update, TinCow, and deleting of the unused areas of our world, will you auto-generate the new areas?

I was wondering if we can have them as black spots for us to explore and discover again. Could be a lot of fun for explorers.

Of course, I understand that the auto-generation was done to avoid ugly chunck errors (Cliffs of Mohang) which happen, when the game version gets updated. So with that we should have the auto-generation of the entire world prior to the update that comes after 1.7. But at least in the mean time we could go exploring. What do you and other people think? Good idea? Bad idea? Is it even possible at all?


(on a little sidenote: the structure I mentioned earlier is at -2850 -980, pretty snow castle, no idea who build it, but may be worth saving)
