So Jason, what is your take? I am inclined to keep queue reset register
and just flip the polarity. Less spec work and semantics are more or
less clear. Not helpful for migration - limited to queue
resize, watchdog and similar uses - but if we are expanding
scope to migration that makes it imo not 1.2 material.
