It mostly affects clients, true.
But to identify the backend user, we use the 'node' since in most cases 
authorization identity == authentication identity.
So what JD mentions is exactly one of the reasons we ended up with issues.

Another being how we look up into the backend store : having '\' in the 
uid is not good if you are writing to a file system as a backend, with 
node as a key and support windows. That way, JID escaping makes us 
require double transformation for those ...
