Alien Covenant:The xenomorph aren't xenomorph (Spoilers)

I'm back guys!!!!I saw Alien Covenant earlier today and have come with theory regarding the xenomorph.Late in the film the xenomorph are introduced Via David luring Christopher Orum into a chamber full of eggs.Now of course we are meant to believe David is responsible for the creation of the xenomorph,but I'm still not so certain.These xenomorph were rather different than those encountered in previous films.It starts with the eggs,they are of course different in appearance from our standard ovamorph.The facehuggers them selves are a bit different too,they are easier to resist than previous facehuggers with the victims resisting even when they are attached to the face.Lope's chestburster even demonstrated an ability to be able to lay an embryo with out even having to fully attaching itself to his face.The chestbursters also had a much shorter gestation period.Then there is the chestburster itself,Orum gives birth to a rather full formed xenomorph rather than the serpent like chestburster we are use to.They also grow a lot faster than usual as well.Full grown there behavior is also a bit different,from the way they move to a lack of stealth (except for the shower scene)These things are far removed from the perfect killing machines we know so well.To me it seems if David is indeed the creator of the xenomorph then he hasn't quite perfected them yet,that these are indeed "Protomorphs."What do you guys think?
