Yes, I noticed this as well. It is unfortunate because as you say, there 
is now no way to identify which instance a Error in SRH is for, and 
subsequently the root node can't just remove that routing entry in a 
specific instance. Instead it must either remove that entry from all 
instances or do nothing and wait for the next DAO to update the entry.
