At least we can all admit that the revelation from Covenant that is David engineered the early design of the xenomorph Will be written out of any fan canon......I expect.
Personally, that whole thing with David and ESPECIALLY the black goo not only destroys the mysterious origins of the xenomorph, it feels like it's a massive slap in the face to origins spawned from Giger's design, even with the deleted scene in Alien with Dallas and the egg morphing thrown into the mix.
I would've preferred the early comic origins involving Xeno Prime, the queen mother, K-series, etc, not Ridley's android fantasy.
