Without it static file serving is practically useless: users can only serve static files from the root or mimic the site structure in the static files.
For example if a FileServer is registered on "/static" and a request comes from "/static/foo.css" the FileServer will not lookup for a file called "/static/foo.css" but for one called "static/static/foo.css".
While this is workable it's definitely not a good UX.
