Thoughts on supporting source maps or something like it? It's very common to use source maps on production code when debugging live site issues and it's nice to have that translation capacity.
Having said that, there appears to be a sourceMaps flag in the Prepack source: https://github.com/facebook/prepack/blob/57cc59c07d164e4827c...
I will be attempting to use this as a simple black box, relying on Webpack for features that are only tangentially related to this new optimization stage in my build stack.
