What I intend to do from here is make a list of all desired use cases,
then ask for people to propose ways of configuring those. Hopefully we
don't need to discuss the meaning of the phrase "sync rep", we just need
to look at the use cases.
That way we will be able to directly compare the
flexibility/complexity/benefits of configuration between different
proposals.
I think this will allows us to rapidly converge on something useful.
If multiple solutions exist, we may then be able to decide/vote on a
prioritisation of use cases to help resolve any difficulty.
