Honestly, there is not a lot of Vim I really miss. Yeah, macros with motion commands are cool, but in many cases VSCode's multi-cursor is sufficient.
Editing code in Vim is probably faster, but that speedup is neglectable if you are missing precise go-to-definition or auto-completion instead.
When it's set up nicely it works great, but any modifications are a pain. Also i can't put in words how much i hate using the mouse, after having tmux+vim+tiling wm set up
I'm building something like that. Feel free to reach out, would love to chat.
If anyone is looking for a side-hustle, I'd be your first customer
