As I understand it, they want to implement vimscript in Lua, not (necessarily) elevate Lua to be a first class scripting language next to vimscript.

Lua already is a first class, built in scripting language in Neovim. (it can be disabled at build time)

I think adoption will remain pretty limited though, because plugin authors want to support vim and neo.

Yes.

No, Lua is not optional in Neovim.
