>the Xenomorph represents an existential threat
It doesn't represent any more threat than a tiger that's smart enough to solve puzzles and open doors. It literally can't get off LV-426 and certainly can't pilot spacecraft. And as stated, they can observe it for decades with no problem or danger. The more they watch and learn about the alien, the less dangerous it is. It's only ever a problem because people didn't know of its abilities and lifecycle.
