I believe it was from your comment on the original page, it said that "War of the Sentinels" didn't really match the event since bad things were happening to mutants even before the sentinels were unleashed. Plus it's a Much better title to cover the whole few decades when the X-Men world went to hell.
I personally think we should keep it as "War of the Sentinels", since everyone in DoFP refers to the event as a war. I've been working on a version of the page that doesn't include info not mentioned in the films, since most of it is background information that the Timeline page covers anyway.
Okay so about the timeline, my main problem is the 1979 section. In the revised timeline part it has the events of X-Men Origins Wolverine, however this is impossible since most of those events have been retconned by the timeline being altered, such as cyclops being kidnapped, wolverine now being experimented on in the 80's instead and deadpool being born 30 years later. Yes Deadpool 2 has this scene, but I saw it more as just a funny moment rather then making that whole movie part of the revised timeline.
I haven't watched the movie yet, but isn't that just a case of Deadpool using Cable's device to travel to the original timeline? So X-Men Origins: Wolverine isn't in the same continuity as the revised timeline, but Deadpool was able to access it through time travel.
For the timeline, people have been adding X-Men Origins events into the revised timeline but that isn't possible. Those events could not have happened in the new altered timeline yet people keeping adding them.
