The configs I tweak are git, bash and emacs, and each has their own way to load extra config from a local file. You can use this for stateful config local to a machine and out of the nix store.

It depends on buy-in from the tool so it’s not a panacea but it works for my use cases at least. I also don’t like to switch config for every change and it turns out I rarely have to.
