I don't think Lua is your average ecosystem. Lua is used as an embedded interpreter. For example, Neovim doesn't want to change its configuration language's syntax just because there is a new version of Lua available.

On the contrary, we can claim that luajit has stabilized lua for implementations and for users (strengthening Lua 5.1 dominance, which makes the experience more homogenous across apps).
