I enjoy occasionally browsing through _The Data Book_, which is mostly a
collection of drawings of then-new bike components from the 1920s
through the 1960s or so. There are countless different brake designs
illustrated. It goes a long way toward proving there's nothing much new
under the sun, at least in mechanical bike parts.

What did you expect? It is just a lever with on one end the actuation and on the other end the brake pad. Only leverage , stiffness an brake pad material can vary (to some extend).

You obviously haven't looked through that book, or looked at the history
of bike brakes. There have been many unusual designs.
