You are right. The filter allows the client to know the length of pushed messages. I believe it was also needed for very long messages. The problem with the default filter was, that the separator was far too common to use for wicket's Ajax responses and the default implementation did not offer a way to change the separator. This was fixed in recent versions of Atmosphere. In fact, changes to the API broke the old one, so I needed to replace it with the improved default.
