The only limitation with CommonJS' Modules spec is that we can't import CommonJS modules by writing script tags during development. On the other hand, CommonJS provides lazy evolution for web apps, with a great module mechanism design. BTW It's possible to load CommonJS code asynchronously by splitting your built code into separate parts.
