Same thing.  It's definitely using v3.  The default is to try 3 then back
down to 2, but I did try explicitly forcing 3 and it made no difference.

Though that does bring up another point: it would be nice if 'mount' (with
no arguments) would tell you what your currently active options are, like
it does for ufs.  I did find some discussion of this in the archives, but
no definitive indication that it was planned (and it's not in 5.2.1...)
