By restricting layouts from accessing the raw request, Next.js can prevent the execution of potentially slow or expensive user code within the layout, which could negatively impact performance.

I don't like this limiting "I know best what's good for you" attitude in my tooling.

Yes limits are desirable to avoid footguns but this seems like too dumbed down of a restriction for little gain.

Do some people prefer using filesystem routing? I don't think I've used it before but it sounds clunky.
