It is expected to give a reply code for every recipient specified. As mentioned
earlier the ICAL object portion of a reply is optional. In some cases, it will
not be possible to build a reply from all calendars to which a message was
delivered. So a reply code like 2.0.7 (QUEUED - the message has been queued for
delivery) could be returned.

yes. That's why you may get a 2.0.7 reply from one RECIPIENT's calendar and an
ical object plus a 2.0 reply from another RECIPIENT's calendar.

It is not specified. This is bad. Any suggestions?

We currently don't have such a reply code, but we could certainly add one.
Seems reasonable to give the sender a clue that the server is at least making
progress.
