I think the problem comes from applying “clean code” as a standard pattern. As demonstrated in the example, extensibility costs in performance, and also sometimes in comprehension. If we apply the “clean code” rules as a matter of course, we pay this price always. In my opinion, we should use interfaces etc at module boundaries only.
