I don't get mails with multiple in-reply-tos, but I send them ;).  I
*do* get mails with in-text references to multiple messages.  For some
mailing lists that I care about (be-devel), I go through and adjust
in-reply-to so that it matches the in-text references.

I think such graphs would be a nice interface to mailing lists, which
gain members not familiar with the lists history.  Browsing a curated
list, finding the critical background for a particular message would
be trivial.

In Mutt, you can tag a bunch of messages, and then ;g to reply-to-all
the tagged messages at once.  I started doing this to get the previous
text from all the messages included in my reply, so I expect this sort
of thing does occur occasionally in the wild.

Attached is a small graph showing two related threads about
bzr+windows.  The multiparent replies allow responses like Matt's,
  "we discussed this last year" message.
