To document the change, I’ll include a syndication link on my website to the permalink for the edit on the wiki. Having subscribed to feeds of wiki changes/edits before the user interfaces are far less than useful/ideal, so having a better contextual bookmark on my website makes more sense for readers while somewhat reformatting things for the readers of the wiki (a related but somewhat different context) works better for that, but still provides bi-directional links and references.
Perhaps I’ll create an edit post kind in the future? For the moment I’ll just post some (like this one) as an annotation? Small steps…
