Not also handy. From the original commit:
----------
     Building and installing architecture-specific man pages only
raises a number of
     problems:

      * The https://www.freebsd.org/cgi/man.cgi is incomplete. As an
        example, it does not show results for pae(4). The reason for this is
        that the cgi interface runs on FreeBSD amd64.

      * In FreeBSD amd64 some manual pages have broken X-refs. See hptrr(4)
        for an example.

      * Also, we have broken links in our Release Notes. This is a
        consequence of the first point. See
        https://www.freebsd.org/releases/13.0R/hardware/#proc-i386.
----------

Would anyone try this patch
https://people.freebsd.org/~fernape/fix-dnoroot.patch?

It seems to work(around) the problem, at least with:

makefs -D -B little -o label=FreeBSD_root -o version=2 ufs.part METALOG
and
tar -c -f archive.tbz  @METALOG

Cheers.
