Registering is not "bad", its just not beneficial. Given that the routes I want to announce are within my assigned range, why is it a good thing to register them? If the transit provider always add entries when I ask for them, it seems to be very little benefit..
The simple reasons is some people (or their buggy router) deaggregated multiple Class B's or A's and broke some upstream providers. You can blame whomever you want, but registration gives the user a chance to notice a typo resulted in 65,535 routes before actually announcing all those routes. No, it doesn't stop a malcious router engineering. But it is a nice "defense in depth" or "speed bumb" for dumb mistake(tm) prevention.
