I think it would be a cool idea if the world was larger and you could see the other colonies villages and visit them, raid them, take over their village or trade with them. It would be a cool concept.
full support
Might be almost pointless though, because the change log already implies a "world generator" is in the work.
We might not get "larger sector", but now there would actually be a "world map" beyond our own colony's border. Something tells me that we also will get the occasion to choose what kind of starting region we will want to start within on the larger world map too.
This said, I believe that once implemented, a world map proper world map could be a -great- starting point for an eventual future multiplayer mode and, who knows, an "adventurer" mode. Colony+adventurer mode players being able to play on the same world in a multiplayer map/server is something that sound like it could be awesome too, in my opinion.
I definitely would love to see this.
However I suspect the amount of work involved in getting whole rimworlds up and running in terms of other settlements, and the whole thing humming in the background whilst we play our colonies is probably too much too expect. It took DF a long time indeed.
I hope in wrong. Someone wave a wand.
Look at the changelog.
Ive posted elsewhere on "world view modes".
Ive got my fingers crossed.
My pessimism is more directed at getting the colonies there and them doing something than the world itself.
