Maybe not to you, but in case of partial failure it will create a new
subthread, confusing participants in the original thread.

Sorry, Richard, that is not yours to decide. This change is OK for
your personal version of Emacs, but in general it is the sender's
decision, not the implementer's. From RFC 5322:
In all cases, it is the meaning that the sender of the message
wishes to convey (i.e., whether this is the same message or a
different message) that determines whether or not the
"Message-ID:" field changes, not any particular syntactic
difference that appears (or does not appear) in the message.
For *most* users *most* of the time, a "retried" message should have
the same Message-ID (eg, if only some destinations failed).
Defaulting to same Message-ID is very safe as long as the content
doesn't change. On the one hand, users are very unlikely to perceive
them as "different." On the other, getting multiple copies of a
message with the same Message-ID is a common occurrance, and any
program dealing with Message-IDs should be able to deal with it. But
defaulting to different Message-IDs does cause harm in the case of
partial retries.
