This doesn't say what's the process of getting all PR increments
applied.

Should we send list of recipes and required PR increments per layer (and
someone will sum these increments and create actual PR bump from it). Or
will we take turns and send actual PR bump patches per layer and someone 
will define order of layers to go in (so that we prevent many conflicts 
while merging)?
