The problem with using something like webpack is that you can't use it for something quick.

You can't dip into the documentation for the one thing you're trying to do, you have to spend time reading a large chunk of the documentation, then going to forums and such to try an understand the history of how that one thing you're trying to do has changed over webpack's history.

Then 5 months later when you're doing it for another project, you have to re-read all that documentation again because one other thing is different.

Compare that waste of time and effort to:

A developer is now unavailable and you are taking over the project. The project uses a modern build-system/module-loader/etc... You need to change one thing to the way to project is built.

You don't have to learn an uber nested spaghetti config file that looks like a domain-specific language. You just read the miminal configuration the previous developer left you and now you know what to change, or how to add the one thing you need to do. You've now saved days of work.
