Huh.  I still have my test results.  Looking back at them, I see that it
always returned an ACL ending in an allow EVERYONE@ entry including
the synchronize bit.

That was several years ago, though, and come to think of it that *may*
have been some translation layer on top of UFS at the time, instead of
ZFS....

Still, I doubt leaving synchronize unset is what they intended, so it
might be worth reporting as a bug if you think it would get any
attention.
