I really like this implementation, although it does shoehorn users into naming their pages with err-<errStatus>-page and limited options for the url of error routes.

Would it be possible to allow the user to define the dir of their choice for errors as well as the component name? maybe to set window.location.href to a ${errPageLocation} or even having an optional JSX Element prop which would return the actual component itself instead of navigating to a pre defied route?

Thanks for opening the PR, but we had to fix this with a different approach to allow for a custom 404 to work and various directories. https://github.com/BuilderIO/qwik/pull/2175
