domainToUnicode cannot be defined in terms of domainToASCII

That would be observable from script. The way they were defined before was rather intentional.

I don't see how it is observable. I can't read your mind.

If you are going to make assertions, it would be helpful to provide accompanying evidence. I encourage you to state reasons, not intents.

You could overwrite domainToASCII and that would change the result of domainToUnicode. This is a pretty common antipattern in web specs, which is probably why @annevk assumed you would understand with that much explanation.

@dominic: thanks!
