Designate has no plans to swap or add support for the new interface in
the near or medium term - we are more than willing to take patches, but
we do not have the people power to do it ourselves.

Some of our users do use the old interface a lot - designate-sink
is quite heavily embeded in some workflows.

Thanks,

- Graham
