Yes, there are USB-C chargers that are made for smaller devices and can't charge a notebook. So what? The alternative would be going back to proprietary chargers that can only charge one specific model.
I have a 100W USB-C-charger in my car, I have one by my bed, one on my couch, one at my desk and one powerbank that can charge my notebook anywhere I go.
Going back to proprietary chargers would mean if my notebook breaks, I can throw all these chargers in the trash and buy a new set. How would that make anything better?
