Upstream is adding handling for utf8 domains by creating a domain alias @utf8 -> @idna. I'm deviating from this approach by setting multiple email address (idna and utf8) per user and alias where a domain contains non-ascii characters. The maildrop (mailbox) remains the same - all mail goes to the user's mailbox regardless of which email address was used. This is more in line with how other systems (eg. active directory), handle multiple email addresses for a single user.
