The problem is finding the right plugins, but it doesn't require that much time (at least in Linux/Mac; Windows may be a different experience).

I use "IDE features" when writing Scala: vim-plug first, then vim-lsc + metals. The configuration of lsc is trivial (as in you can copy an example of less than 10 lines).

After using this for a while, I replicated the same experience in Python with python-language-server (I install it with pip --user), and it was matter of 5 minutes to setup. Before this I was using syntastic + ctags, and that required much more work.

May be is more work than getting the same functionality in VSCode, but it doesn't look a lot of work to me.
