Unfortunately Browserify says you can't make global transforms from package.json:
https://github.com/browserify/browserify#btransformtr-opts
"If opts.global is true, the transform will operate on ALL files, despite whether they exist up a level in a node_modules/ directory. Use global transforms cautiously and sparingly, since most of the time an ordinary transform will suffice. You can also not configure global transforms in a package.json like you can with ordinary transforms."
