Assuming you don't know which hosts implement and use SEND this is
equivalent to saying  it works when all the routers and all the hosts are 
on the same side of the ndproxy. Since nothing connects to the other side 
of the ndproxy I think you can disconnect the ndproxy as well.

The IPv6 WG charter has:
Jun 04  Submit Proxy RA to IESG for Proposed Standard.

So we are not that lucky unless something changes.
