RFC 4282 defined

which means a single-label Unicode string would be absolutely fine

Potential problems with global use of single-label names go beyond SMTP.
For example, RFC 4282, which defines the Network Access Identifier
(NAI), does not permit the use of single-label names. From Section 2.1:
realm = 1*( label "." ) label
As a result, someone purchasing the "example" TLD and using the NAI
bob(_at_)example in order to obtain access to the network, might well
discover that this would not work.
