I'm not the target for your question (I distribute 0 plugins).
But Lua support in Neovim is the primary reason I moved over from Emacs. Elisp and Vim are both so heart sink for me.
That said I'd have preferred something other than Lua if I had the choice.

Same. I know we as a community would never agree on what that language should be, but in my dreams it would have been ruby. Even javascript would have been better for me than Lua.
