Not only does it makes the code more robust and correct as it allows error propagation, it allows us to enforce timeouts on waiting loops so we don't hang forever, by waiting for the i8042 controller to respond to us. Therefore, it makes the i8042 more resilient against faulty hardware and bad behaving chipsets out there.
