Re: [whatwg/url] Refusing a mix of numeric-only and BIDI domains (#543)

annevk left a comment (whatwg/url#543)

We made a change here whereby none of the domains in OP end up rejected because they are all ASCII: https://github.com/whatwg/url/commit/a8d5ca3716c31145d103d83d1cae65a881dd4d7a. Chromium never implemented the UTS46 validation the URL standard required for ASCII domains and WebKit ended up reverting that work due to having to match Chromium. It's expected that Gecko will align in due course as well. (I find this all rather unfortunate, but such is life.)

So if we make changes here that would only impact non-ASCII inputs at this point. I agree with the above sentiment that an exhaustive set of tests and their results (before and after the change) would be a good way to judge a possible change here.
