Yes this is something we need to clarify further. But AFAICS currently 
the purge logic is in the way since it causes the two base states to 
diverge. See also OAK-659 which is about moving that logic down below 
the NodeBuilder interface. It's not clear to me how to do that though 
since we don't have the information about the transient moves at that 
level and restoring it from looking at the content diffs doesn't work as 
discussed several times before.
