Do most vim plugins work without changes in neovim? I'm mostly using vim-airline and tagbar to be honest, wouldn't be sad if the other ones stopped working.
VimScript is not deprecated in NeoVim, and maintaining backward compatibility is major focus. So must Vim plugins will work in Neovim. vim-airline is listed among the plugins that has some special neovim-specific features added:
https://github.com/neovim/neovim/wiki/Related-projects
- vim-plug for a plugin manager (very good regardless of concurrency)
- neomake for building
- vim-go added async job support using neovim a while ago for most of its functionality, which I use for writing Go
