Ah.  Here we are:

contrib/tar/src/extract.c, revision 1.2 (07-Jun-2002) by sobomax

+#ifndef __FreeBSD__
    same_permissions_option += we_are_root;
    same_owner_option += we_are_root;
+#endif

This disabled -p as the default for root in FreeBSD
builds of GNU tar.  This change was first released in
FreeBSD 4.7 as far as I can tell.

This does beg the question whether bsdtar should
follow FreeBSD GNU tar or FSF GNU tar?
