Requests to none Cloudflare sites with path /cdn-cgi/ fail
A worker which requests content from another site can't access paths starting with /cdn-cgi/ because Cloudflare handles these. Is there any documentation for this problem and why does Cloudflare even handle these requests? Example Worker 
export default {
    async fetch(request, env, ctx) {
        return fetch("https://myip.wtf/cdn-cgi/trace");
    },
};
export default {
    async fetch(request, env, ctx) {
        return fetch("https://myip.wtf/cdn-cgi/trace");
    },
};
Expected output 
No such *** page!
