The goal is precisely to not just bundle, but incorporate important optimizations like the V8 Compile Cache (https://github.com/zeit/ncc/issues/51), which is what inspired the project and name to begin with.
It would make more sense as a collection of plugins, and perhaps exposed as a preset.
But the intent is to precisely remove the extra setup, when all you need to do is publish your Node.js codebase as a single file.
