But that loses its usefulness if there's new tools every 6 months. Yes webpack gives me structure today, but there could be a new structure tomorrow. Look at Grunt and Gulp, NPM and yarn....
Not really, you'll still be able to follow what's going on if the project follows an old standard way of doing things, compared to a random or made-up way of doing things.
I had to update a project that used the Gulp-based workflow 2 days ago, and after 5 minutes I knew what I was doing again.
Even if you don't remember you can still look it up, while those who reinvent the wheel seem to never bother documenting their wheel.
