Grunt has a very slow building process. Gulp should replace Grunt as the recommended method for building static assets.
This would also be a good time to decouple PHP calls from the nodejs build process. Any PHP calls from nodejs should be moved to ./bin/magento so node/js code is kept node/js only, and PHP scripts are only called from PHP. This will help streamline the deployment process.
