Comment (by pdfernhout):

 As a caveat for any fix for this issue, issue #25233 from two years ago
 says: "Currently WordPress loads all the revisions in order to possibly
 upgrade them to the 3.6 versioning of revisions. It does so on every post
 loaded in wp-admin. It might make sense to move this to an upgrade routine
 or somewhere else as it adds to the performance degradation." That issue
 mentions other things to consider as well.

 I am not sure if that specific concern on upgrading revisions applies here
 or if data corruption/confusion could be a possibility somehow if that was
 not done and a very old post was editied. But it seemed worth mentioning
 in case upgrading all the post revisions was a crucial (but undocumented
 in the code) side-effect of counting revisions inefficiently in the
 original editor code?
