In short, the answer to this question is NO.
The WordPress revision history itself is a resource-hog and if you want your site to be fast, we recommend to turn them off as they cause database bloat.
Revisions tend to cause database bloat, which in turn causes slow performance.
Keeping a revision history with courses that can span over 100's of Lessons would be so resource intensive they'd slow the site down alot.
That is why we do not recommend it.
What if you Need a Revision History?
If you need a revision history as more authors work on one course we recommend using an external content redaction tool like google docs or Evernote or similar.
Only copy content over to your eLearnCommerce Platform after it has been approved for publication.
