Steve Bate@evan To be clear, I'm not saying Mastodon per se is broken wrt Updates. I'm saying change tracking is problematic in the AP recommendation. An Object URI will always reference the latest state of the Object, not the previous states for previous Updates (all referring to the same `object` URI). The Update could have had the changes as the Activity `object` and the target URI to update as, well, the `target`. Then the history of changes could have been preserved.
