 Review comment:
   I see your point and I understand how to check the header and properties 
encoded size without costs from your example. In that point large message 
contains only header and properties of the source message and in addition it is 
precisely the record that is added to the journal. I think the last point is 
important because it let the check to work even if in the future other elements 
will be added to the large message.
