I don't think it's thin even in that context. For example, invoking a hook comes with a bunch of rules beyond "just javascript". You shouldn't invoke a hook conditionally. You shouldn't invoke a hook in a loop. I've run into state/props mismatches due to the diff resolving differently than I thought it should. It's possible to solve this, but it further breaks the illusion of a thin layer. Maybe it's a different way of thinking, but I don't think two-way binding is inherently thicker. To me, thickness is related to the amount of "mechanism". A handlebars-type templating system seems much thinner to me.
