when fingers 'touch' routers, bad things are bound to happen sooner or later.
I wouldn't disagree with you. It would seem that the more complex the network, the more automation and abstraction is required. Few would disagree with that. But then, if configuration of routers is automated, it would seem even easier to implement the route filtering. Verio has a history of being a prefix length nazi, but were they that way about route validity? Plenty of networks are stringent on what they accept from their customers, but are they as stringent with the routes they send? As long as people continue to have unfiltered peers (save for maximum-prefix), this would seem a reasonable measure of implementing the principle of being liberal with what you accept and conservative with what you send.
