I'm not really sure that would be a lot better. My prefered solution is to
just add -P to the extract args unconditionally (as this restores as close
to what we had as previous behaviour). If there would be an explicit
symlinks option I'd use that (unconditionally), but for our sets it does
not buy us much.
