--- Comment #428 from Sebastian Lackner sebastian@fds-team.de --- Closing this bug was probably a bit rushed, to quote Andrews comment on wine-devel:
"""After those five, there are three more patches to implement missing critical interfaces (volume, session, and marshalling)."""
I would assume the current state is not fully functional enough to actually use it.
