I'm not aware of said functionality on the client-side. Out of curiosity, do you mind linking me to said documentation or article on how to circumvent routing on the client-side without using fs-based routing?

That is through using a custom server -- which is a whole other topic. I'm comparing apples-to-apples between NextJS's built-in router and Remix's usage of React Router as far as client-side routing is concerned.
Actually, that's not true. You can opt out of the fs-based routing altogether.
