There was a change near the beginning of November; please see UPDATING
entry 20171101 -- you probably have several no-longer-used
subdirectories under /usr/obj/usr/src/.

Once those are cleared out, my experience (tracking stable/11 & head in
different slices on the same machines) is that stbale/11 is using about
5.0G, while head uses about 6.1G.
