   I am wondering if the above restriction is necessary. Server is just 
responsible to return events since the provided continuation token and applying 
the client provided filters on top of the change events. If clients choose to 
change the filters, that should be fine although I am not aware of such 
scenarios yet.
   
   Also we probably should replace `next-page-token` to `continuation-token`.
