Bundle size analysis on catch-all segment routes

TL;DR

Important

Client-size routing using catch-all segment routes will negatively affect your bundle size

Doing client-side routing on a catch-all segment route will increase the bundle size of that route as it will include all the components and their deps. Next.js can't optimize the bundle because the routing happens at runtime, not at build time.
Having individual routes results in smaller bundle sizes because Next.js can analyze them at build time.
