And yet in Spider-Man 2099 Earth-928 was the "possible future" being altered by changes to Earth-616, in Spider-Gwen Earth-8 was the "possible future" at risk of being altered by changes to Earth-65, and in Thanos "Earth-TNR666" was erased by Thanos going back in time and vowing to never become King Thanos.

I think I remember there having been several discussions regarding this topic in the past, with the consensus being that the wiki tends to disregard retcons - particularly those that contradict what's outlined in the databooks, and several writers have made it clear they couldn't care about the what the wiki considers canon or not.
