Your minification process should be separate from your build process that's required to run it. This can generate JavaScript that's not a huge pain in the ass to debug, then you as the developer can minify it with existing libraries. Though I'm not necessarily sure it wouldn't be high performance just maybe a hair slower to load. Then again I don't know how well their generator works.
