I think there are some differing assumptions on the impact of replication. My assumption has been that replication would be a new feature that was 'optional' in that R=1 would not be significantly from what we are doing now. Thus replication work could continue in trunk -- and even be present in releases -- without being disruptive, the lack change would just be to allow and document values of R > 1. However, both Jay and Jun's description of the work make it sound like more of a backwards incompatible no-rolling-restart every broker/consumer/producer needs to be upgraded at the same time sort of change.
