I am sorry I could not be there. I am in Hangzhou, and the ccommute would

What Mark said. There is only one justifiable case for conversion, and it
is very much an edge case.
However, anyone who is giving out multiscript addresses should probably
consider mapping the punycode conversion of an address to the same
account, just like some providers will map chaals.nevile@ and
chaals_nevile@

This seems reasonable to me. I have had chaals@яндекс.рф as a working
address for some years, and I would be upset if you tried to take it away
:)

This seems reasonable in general. It might be worth suggesting that mail
providers look into mapping confusable script combinations - chaals and
сhаа1s - and blocking the registration, or insist on a clear
non-alphabetic divider character à la epoc(ерос) - even in the common
legitimate case I see things like chaals(茶人生).
As noted, there are few problems in most script combinations, but there
are some combinations that have both potential confusability issues and
legitimate uses like chaals-чаалз@
