On my home site of RPG.SE, I'm trying to investigate whether a particular tag might be causing trouble. Specifically, I'm trying to find all the questions that had that tag in the first revision but don't currently have it, and vice versa, to get a metric on how often it needs to be added/removed.
However, SEDE doesn't seem to store revision history about tags. As far as I can tell it stores tags only for the current version of a post, and for revisions it only stores the text, revision comment, post ID, and some metadata around the revision.
Does the data explorer actually store post tag revision data somewhere I'm not seeing it? If so, where does it store that information, and how do I query for it?
