Perhaps an opportunistic execution of afsctool on just-extracted (not
yet moved into place) files in portimage.tcl (similar to the
opportunistic use of lbzip2 or pbzip2 during extraction) could be
done? I'd tend towards find + xargs (possibly with -P <jobs> to speed
things up) but any number of approaches would work. Should likely be
controlled (able to be forcefully disabled) by a config option and a
check that the filesystem is HFS+.
