No one needs to re-invent a monstrosity that is ib-verbs. If anything,
that is a model that should never be recreated again, showing that we
can learn from past mistakes :)

I agree, don't try to duplicate the mess that people moved away from
(hint, everyone sane wraps ib-verbs in another model that can actually
be used and understood...)

Sure, that sounds like a great goal!
