That's not really a solution.
1. Vandal puts something oversightable in some template used on many pages. 2. People, not realizing it's in the template, edit the many pages trying to fix it, getting these bad old versions in your cache. 3. Template is fixed. Do you reparse the many pages, breaking the whole idea behind your "archive parsed versions of old pages" plan? Or not reparse it, requiring wiki users to go through all million transclusions of the template to see if any revisions were vandalized (and still missing the ones where the current version no longer transcludes the template, even though it did earlier) and manually suppress them?
Option (a) would be workable, although bitrot might be a concern.
