Bayou[1] is the canonical example for this kind of service. We have the
benefit of not writing to our replicated datasets, obviating the need
for conflict resolution.
I agree that this probably isn't a feature we want or need right now.
However, lazy replication of weakly consistent datasets is a fairly well
understood problem.
