In other words, do you care about script loaders? Are they useful?
Yes we like script loaders, wether we are bundling or not. They help us to keep our projects neat and organised for one thing, and force us to be modular with componenet scripting, they also help us to keep things correctly/safely scoped, out of the box.

With HTTP2 they might be more useful - with HTTP2 you can keep them as separate files instead of concatenating them into one giant JS file, you can load only the files you need to load and speed up startup time. With HTTP2 you will have a single connection through which everything is loaded instead of opening many connections to load files.
