Now I know this is likely to ruffle some feathers but that is not the intention of this post. I simply want to have a discussion around these ideas.
Many people use examples from The Weyland-Yutani Report to argue against AVP being canon but I find you can do quite the opposite. The Weyland-Yutani Report canonizes the 2014 Alien Novel Trilogy with it's reference to the events of Out of the Shadows and River of Pain (mentioning Captain D. Brackett by name).
Out of Shadows introduces an alien species other than the Xenomorphs - the Drukathi. The Drukathi play an important yet mysterious role in The Rage War Trilogy; an AVP story. The first book of the Rage War - Predator: Incursion mentions the events of Sea of Sorrows when Weyland-Yutani has been running a successful Xenomorph research program aboard the USS Evelyn-Tew following the recovery of samples from New Galveston.
River of Pain also makes reference to the comic series Fire and Stone when Anne assumes Cale, Dione, and Russell had slipped away to get to the Onager, an excavation vessel that some colonists of Hadley's Hope used as a makeshift escape vehicle to ferry themselves off planet when the colony was infested in Aliens: Fire and Stone.
So if you consider The Weyland-Yutani Report canon does that also make AVP canon?
