No, I don't think it does. Daniel's change introduced new protocol
elements to get the new atomic behaviour, a old client using the old
protocol still gets the old non-atomic behaviour.

We could change the behaviour associated with the old protocol, and then
we could backport that relatively small change to 1.6, and that would
allow the script to work. That would be the regression/improvement I
mentioned.
