furthermore, you don't seem willing to accept or act on negative results, as evidenced by your continued insistence on using LIST: despite having been informed that it confuses one widely used mail user agent.

It confuses Gmail, too. Gmail displays the recipients (and addresses the replies) as LIST, ietf-822

I suppose as a well-behaved beta-tester I should report that as a bug.

Perhaps. But group syntax has been so little used in the past years that IMO it's better to kill the syntax than to try to support it. As a feature, group syntax simply isn't carrying its load.

IMO, the best option would be to issue a short RFC saying:

1. Mail senders SHOULD NOT generate group syntax.
2. Mail receivers are urged to test that they can parse empty groups, since several current senders generate that, e.g. "To: unknown-recipients:;" and "To: ietf-announce:;".
