One could argue the QoS part is also I/O independent, albeit sitting
"on top" of the I/O,
unlike the protocol handling. And the ability to mock the IO, would
allow testing and fuzzing
the QoS in a way that would be more difficult when it mixes with the
I/O, unless when using
sophisticated simulation frameworks for I/O, requiring possibly
specialized kernels or hardware.
