Request: Keep last X revisions

While the “keep last X weeks worth of data” is useful, it would be more useful to have a “keep last X revisions” so that there is always previous versions of posts.

If an old post is corrupted or saved improperly (e.g. by a new employee) we may not notice for a while. So if I notice a problem at week 3, but Wp Optimize is set to 2 weeks, the old version of the post is gone forever.

Would be more safe if all posts had at least 1 previous revision that we could restore.
