Do people use Nix for building and deploying project dependencies? Example project? Can you consume the result in a format that isn't all Nix-y symlinked?

nixpkgs contains tools for building Docker-compatible container images with `dockerTools`, and also AppImage-style standalone executables with `nix-bundle`.

My project, as well as many other projects, ships its own default.nix for builds. Linking an example would deanonymize this account a little too much, but there's plenty of examples out there.
