Re: [whatwg/url] Malformed URL Normalization in Standard Introduces SSRF Risks (Issue #893)

the-moisrex left a comment (whatwg/url#893)

Yes, I'm aware of that. And that is the point. Any modification to the href should make the string **Not Normalized**.

And using the term **invalid** for `http:127.1` is not exactly correct either. We could consider them as non-failure errors, but not errors. 

Ada-url for example simply ignores these non-failure errors AFIK. In my implementation which is a work in progress, I have them as warning flags.

`special-scheme-missing-following-solidus` non-failure validation error is only about `file:` scheme not having slashes, not other special schemes; maybe there's something there!
