That is fantastic, on first glance it seems exactly what is needed.

I just think it's unfortunate that the tool needed someone to develop another tool to make it truly usable. Good software should be simple to use and configure, not dense and opaque.

I don't think it's unfortunate, I think it's a good abstraction. Webpack being a lower-level tool wrapped by Neutrino. Similarly to git's plumbing and porcelain separation.
