    Perhaps to give the master more control over which data byte lanes are written to the slave ?

    AWSIZE tells the slave by how much to increment the address in multi-transfer, non FIXED bursts, and WSTRB then tells the slave which of the byte lanes described by the AWADDR/AWSIZE/AWBURST combination contain the data the master wants to update in that transfer. 

    If you don't need to perform sub-AWSIZE indicated transfers your master can always just assert all the WSTRB bits described by the AWADDR/AWSIZE/AWBURST combination.
