This hasn't been decided yet—I'm aware how much people appreciate the vim bindings, but they are _huge_ (as big as the current core) and written by someone else. I'll probably take a stab at porting them when the new API is stable, and give up when it turns out to be too messy. On the bright side, they have a lot of tests, which helps with making sure I don't break them. But they _are_ still looking for a new maintainer, and even if I do port them, I'm not taking over maintenance.
