I think the issue might be the name "tree shaking". People from outside of the JavaScript just don't understand what it means, and how important it is. Maybe we should have just called it "dead code elimination". (I think there is some subtle difference but my memory is failing me).

IIRC tree shaking is a form of dead code elimination. Something like: dead code elimination is the what and tree shaking is the how.
