Yes, that is probably a better way of saying what I was trying to
drive at. There's a significant portion of kDAPL that doesn't seem
necessary or useful to me. For example, why do we need a new API for
posting work requests? Why do we need the ability to combine
completion events and CM events into a single queue?
