Nice read.
I see the use of curated library (white-list regexps, with some heuristics, perhaps context-aware) that can be shared among tools such as browsers or command-line tools, so that they refuse with a warning of a suspicious idn is used.
But I don't see the need to ban any 📯 emojis there.
If needed, the user shall of course be able to bypass such warning, but no short should be tolerated (--bypass-idn-check, not just -b).
