tar simply creates a file on disk.  For each file it archives in that
file, it records some information about that file, including the file's
owner and group.  The suggestion was that pax should have a flag to
record some other group in the tar file.

Obviously, one would still need to be root to unpack the tar file and
actually create files with that ownership, but that is another matter...

Note that when package sets are integrated into NetBSD, there is a
_strong_ argument for having the build process create (as non-root)  
package sets under a ${DESTDIR} and pkg_add them (as root) to the actual
system rather than install in place...
