If the sender knows the size of the message upfront then there is no point to fragment it. The sender can just specify the total length of the message and keep pumping data into the connection, while the reader can count the received bytes and so know where the message ends. The whole reason of having fragmentation and framing is to remove the need to know the full size of the message prior to sending it.
