I agree with the proposal; these are just some nits.

          ...meeting to drop sS10.1 altogether...

The sequence "s^HS" appears here, and in several other places - is
this intentional or a bizarre result from "nroff"?

[ It's nroff's attempt to produce a section sign.  The actual note
will be formatted with troff, which can handle it.  I will incorporate
your other comments.  -mod ]

            4.  Hard links are not handled well, since cpio format
                does not record that two files are linked.  If two
                files that are linked are written in cpio format, two
                copies will be written.  There is an option to the
                cpio program to detect duplicate files by matching
                pairs of (h_dev, h_ino) and producing links, but that
                is done after the fact.

Actually, this is the standard way "cpio" handles hard links; it's
not an option.

            5.  Symbolic links are not handled at all, and no type
                value is reserved for them.  This makes cpio useless
                on a large class of historical implementations (those
                based on 4.2BSD or its file system) for one of the
                main purposes of POSIX sS10.1: archiving files for
                later retrieval and use on the same system.

(Another s^HS here)  It is possible to extend this format to handle
symbolic links; we have done this.

[ But remember that what was proposed to P1003.1 was existing System V
cpio format. -mod ]

                ...However, cpio was not available outside AT&T
                before the release of System III, while tar was in
                wide use with Version 7 and is still much more common.

Actually, the old "cpio" was available with PWB/UNIX 1.0, which AT&T
did release.

                Also, it appears that the cpio format of PWB was not
                the same as that of System III.  <V11N39 Henry
                Spencer> Although System III and perhaps early
                releases of System V did not include tar, <V11N26
                Joseph S. D. Yao> current releases of System V do.

No, System III and all releases of S5 included "tar".
