Maybe they thought: "If we include this deleted scene, people are going to pissed and think we violated the canon! So, uh, we won't show a queen, but, like, we'll show a bunch of eggs and alienses...that way it isn't shown but not contradicted either! D:". After all, not everyone knows what egg-morphing is. Some people literally think Predator came before Aliens and that they've always been part of the Alien universe.
