if it were clear how to do this out-of-band, that would work.

as i read the 0-10 description, messages are not fixed size, but  
rather the fragments are, and together with the first/last fragment  
properties 'eventual' sizing is accomplished in a clear way.

for 0-8|9 it is not clear where this information would travel safely.  
no publish argument permits the sender to specify a value - unless  
one overloads the routing key. the equivalent "place", the body  
header properties for basic class content uses 14 of the first 15. is  
it acceptable to add properties to the content header?
