When the risk is extermination of the species ‘pretty good mapping’ doesn’t cut it.

  There's a fair amount of chaos/uncertainty in orbital mechanics, so perfection may be impossible. Also, the smaller "city killers" can be very hard to spot, especially if they're in the wrong position relative to the sun, but those aren't extinction level. That said, I would think runaway climate change or nuclear war are much greater threats to civilization (though humanity would probably survive in some form), so those are probably where the effort should go if survival of human civilization is your thing.
