What I'm still holding out for is an _embeddable_ NeoVim. The thing I really don't like about IDEs is that I love my Vim configuration but I never get to actually use the damn thing since I do most of my work in an IDE. Now imagine if the IDE could actually just embed NeoVim, and I could use my Vimrc as-is with all the plugins (now managed natively). I know they already have Electron-based UIs for NeoVim, and Electron-based IDEs, so hopefully it's just a matter of time.
That said, does this actually put NeoVim _behind_ in terms of feature parity?
