Sigh...  It completely fails to mention descriptor-passing.  Which
a) is relevant to what "last close" means and
b) had been there for nearly the third of a century.

Why is that different?  These clearly count as file descriptors.

To quote your own posting upthread (Message-ID:
[ref])

Well, a file descriptor really only exists in the context of a process; 
in-flight it is no longer a file descriptor as there process context with 

  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

a file descriptor table; so pointers to file descriptions are passed 
around.

IMO it shows that the wording is anything but clear.  The only way to claim
that it's accurate is, indeed, to declare that the contents of in-flight
SCM_RIGHTS datagram should be counted as file descriptors and that's too
much of a stretch for the reasons you've pointed to.
