Peharps the request just meant ROW format.
Then not to transfer only updated fields of a record one also needs 
--binlog-row-image=MINIMAL.

I wonder whether your use case might actually be something like COLUMN 
replication.
That is when a master M table record
                              
M:  <A INT, B INT, C INT> 

is updated subsets of its columns
are replicated to different slave servers. E.g S1,S2,S3 that subcribed to
a single column could receive it as

S1: <A> 
S2: <B>
S3: <C>
