I think it would be good to have a design document, just to reason
about it and make sure that the mechanism we are introducing is not
flawed. It is easy to get these things wrong.

Thanks to all of you that responded. This feature is also important
project I am working on. Although we would have to find someone
right skills to contribute to it.
Henry, Do you have an estimate on how long this task would take if

107 is still pending. Henry was interested to implement this, I'm
his current status. Henry? I think this is a good feature to add,
brings up a number of issues that we need to work through. Given
ppl rarely change cluster membership, and the fact that there are
available today, there hasn't been a lot of demand for this.
