At one point, I had wondered about separating out the client and server
support as well. At first glance, that would seem to help move things
forward and would address most of the reported use cases. However, I
have some users who would need the client support as well.

I suspect that adding the server support first might be a problem for
the developers. Such a feature would need regression and unit tests, and
those would be easier to implement if the client has support for the
feature.

It would be nice to know what the precise technical issues are that have
prevented support for this from being added. From what I recall, it
seemed like the delay was largely due to details of the client
behaviour, and possibly some feature creep.
