I like to think of a nix-shell as a messy stateful environment to 
install all sorts of things, and a user-profile as a slightly less messy 
stateful environment. It's like the IO monad of Nix. So right now you 
can use config.nix to install and rebuild packages, while using other 
ways to manage config files.

Note that there are many parts of the OS that is still not completely 
declarative and pure-functional even when using configuration.nix. But 
it's better than nothing.
