I agree with Alan.

We need to port the instances where this API is used to the new way including the tests. In the process of doing that we'll eliminate the possibility of releasing something that isn't useful/useable. We won't know that until/unless we do the work ourselves.

Don't worry about the time too much. Let's do the right thing.
