Clarification on the modularity of Polymer within external web component scripts: Is Polymer designed in a way to export it as a (commonjs) module? #666

I'm trying to figure out how whether or not polymer library users can wrap around Polymer to make it a node-style module in order to create an external script for a web component with libraries I hope to load in as modules using browserify or a similar module tool.

my-custom-element.js

let _ = require('libraryA'); 
let Polymer = require("polymer-module"); 

Polymer('my-custom-element', {
  // my-custom-element's properties and methods 
})

polymer-module.js (browserify-style)

module.exports = ????

I thought it would be simple as creating JavaScript or CoffeeScript file that exports the Polymer object, but apparently not since the polymer.js file begins with stuff like window.PolymerGestures={}.

Since most will import polymer.html, are we expected to not overthink it and merely import anything else we would like to add in our Polymer function declaration to define our web components however we like (requirejs, browserify, and whatever else) instead of having to account for it being anything different in our external script tags (even when minified)?
