Well, it does simplify the MTA's job. Instead of all that queueing and retrying and such, you just have during SMTP (hold on a minute while I attempt to deliver this to the next hop and return that result to you)*N, a system that doesn't seem to scale well. Either that or you just forget the concept that the originator of a message can ever be informed of a delivery problem.
You are missing the point. Of course you can inform of a delivery problem, but only when you really need to do it. Every organisation should know of every recipient within their authority. You should know the recipient if you accept a message for delivery from outside your domain.
