It does not _attempt_ to define this set, it only _allows_
to define this set.
But as the sender of mail, and the person affected, it doesn't
allow *ME* to do so. If -- in a fit of stupidity -- somebody at
the ISP where I *receive* mail were to do so, I would either be
forced to use a null return path (breaking the intended function
of delivery notifications, as noted by Markus), or I would drop
that ISP like a hot potato and find one with more sense.
I'm a strong believer in "their server, their rules", and also "the
domain owner's domain, their rules". If your ISP does anything you
really don't like, I complete agree that you should switch. For only
a few bucks a year, you can also buy your own domain name and then you
can set the rules for the domain you use.
