That would be a fine thing, but the user has only two ways to express his
desires: one is by injecting routing information, which necessarily can be
overridden.  The only other way is by doing a setup protocol.

Some folks have proposed a hybrid architecture in the past that allowed
both, but it (rightfully) went over like a lead balloon.

If they are advisory, then the ISP may ignore them.  It was previously
asserted that this would be unacceptable.
