Legend
Let's look at Ravenloft. Prior to VRGtR, did any of the things you mentioned invalidate pre-existing lore for that setting? Did history not happen? Just in 4e, and even there it doesn't change the actual domains of the setting, just where they decided to drop them.
Expedition to Castle Ravenloft. An official 3.5 D&D reimagining of I6 that changed huge swaths of the lore. It absolutely ignores everything in the 2e setting and reverts it back to the 1e "Castle setting" devoid of Mists and Powers.
Want a different example? Tiamat. She went from Lord of Avenus to deity chilling in Baator to prisoner of Asmodeus. Sometimes she's Takhisis, other times she's not. Sometimes she's a full goddess, other times a powerful dragon. Then again, Orcus, Asmodeus and Lolth are all sometimes deities, sometimes powerful fiends, and sometimes dead.
D&D lore has the consistency and purity of a random harlot table. Most media properties that are 40 years old or older do. Holding them to a standard of consistency in their lore is a fools errand.
