This looks like built by someone raised exclusively on web and touch technologies, forgetting that both are the results of constraints. The web was not meant to be a UI platforms and have poor primitives, and touch devices lack precise positioning and a physical keyboard.

Take the chips and rating as an example

It’s purely aesthetic as functionality (and ux) wise, chips are not different from checkbox with labels and rating is just a discrete slider.

And as I thought, you can see the duplicate code for switch and checkbox here.

People do need to differentiate between UX primitives and something that just looks different.
