We now use webpack instead of SystemJS, effectively bundling modules into one file (plus commons chunks) for every entry point. This results in a much smaller extension size (almost half). Furthermore we use yarn/npm even for extension run-time dependencies. This relieves us from manually vendoring and building dependencies. It's also easier to understand for new developers familiar with node.
