Eventually, the initiator has to give up
waiting and ACK the pending byte.

Whatever byte count may usually be
associated with a particular CDB or data
header, the target may still decide to drop
out of data phase prematurely.

Sure, can happen.

Does happen at the end of each phase, and is
quite likely to happen at the end of a data
block if the target has full data buffers.

Again, eventually, the initiator has to give
up waiting and ACK the pending byte(s).
