 And what is the use of ACK*?

 Note that that the state of the CPU at the moment of a write is
completely unrelated to the action that triggered the write.  Therefore
any reporting of a write failure is hardly useful -- possibly as a kind of
an MCE only, i.e. report the event and kill the current process or panic
if none.
