For 14.n - no to all
For 15.1 (coming out end of May) - ZFS - yes to all, UFS and TMPFS -
yes for archive/hidden/system
For 16.0 (which is at leas 18months away) ?? (unlikely to change except maybe
  named attributes for tmpfs)

Note that exporting of tmpfs is not a good plan imho, since the
changes are all lost when the system crashes.

Note to other readers..this only affects Windows NFSv4.n client(s)
(and maybe the MacOS NFSv4.1 client). (I can't afford a Mac, so
I have no access to one and Apple doesn't talk about NFS support,
so it can only be determined by testing. I am not sure if what Microsoft
calls the Exceed client is affected or not?

This is not something typically in a FreeBSD man page.
