Erm, DNS uses Punycode because it comes from a time when Unicode didn't exist, and bind assumes a grapheme has no more than one byte.

Yes but I guess that the message was meaning that browsers now detect homographs and display the punycode instead. See also https://news.ycombinator.com/item?id=14130241; at that time Firefox wasn't fixed, but in the meantime it fixed the issue too (there's a network.idn.punycode_cyrillic_confusables preference, which is enabled by default).
