Hm, we could have the best of both worlds if source maps (can already be served to browsers and are supported fine) could be proven authentic. I believe right

Hm, we could have the best of both worlds if source maps (can already be served to browsers and are supported fine) could be proven authentic. I believe right now, I could use foo.min.js and serve you a cruddy foo.min.map.js to mislead you. If I served you the original sources foo.concat.js and a build script to go from foo.concat.js => foo.min.js instead, we could have both the speed of the minified version and the (proven by the browser) accurate source code and maps!
