I don't mind, but I currently use Fireplace for Clojure, Intero NeoVim for Haskell, and the vim-fsharp plugin. As far as I'm aware, there are no direct ports of those for Kakoune.
Fair point, Kakoune still lacks when it comes to in-depth integration with tools for specific languages. There is good LSP integration but unfortunately LSP alone won't turn editor into IDE.
Do you mind listing plugins you miss? That's probably depends on use-case but my impression is most of essential stuff is already available.
