I agree, and it's a bit surprising that it isn't talked about more. I still feel like it's overall a win compared to Vimscript, in terms of readability and maintainability, but there's definitely an enduring awkwardness to customizing the editor using Lua.

That's fair enough - I used it on Linux, and I don't care too much about font rendering, so it works out for me.
