Even though I know it'd be better, I can't rationalize the time investment needed to port the subset of distribution that I use into a standalone config. Despite being very opinionated, I think spacemacs gets many things right by default, for example everything being evilified, linting and code completion working out of the box, the popup that shows all possible next code sequences, etc.
I do wish there was something more lightweight, but until I'm annoyed enough about that, I'll stick with the current state.
