NOTIFY_ON_EMPTY is in the MAY be offered category. I'm still wondering about the old legacy bits. Transitional devices not offering them is easiest to implement from the host side, but I'm wondering if all legacy devices will...

Basically we expose through modern interface a superset of bits exposed through legacy.
