We're still trying to figure out the best way to implement those. There's a prototype, but it hasn't landed in master. It's definitely on the roadmap though.
The major innovation of kakoune, imo, is to combine modal editing with multiple selections. These are two very powerful concepts that haven't been combined well before, to the best of my knowledge. In any case yes, I think kak is a great editor and a definite source of inspiration.
Sounds cool! I don't know what to say about Vim-like. At this point I think it's mostly a dream that one day, something can replace Vim. Not saying it's perfect, it's just so entrenched, and full of features.
That said, I don't think I'd be after a perfect Vim copy. I think I would like an editor that uses the same approach, doesn't have to be exactly the same keybindings.
