I think that the closest we can come in practice to such behavior is 
merging. Since the MCM updates are merges, you get that precise behavior 
when using multiple repositories. In other words, if there were a 
conflict in the updates to 3.11 and Seaside 2.9 the update process would 
open a merge browser and leave it to you to decide what exactly you want 
to do with it.
