Comment (by rmccue):

 Replying to [comment:67 rmccue]:
 > > Hm, `wp_save_post_revision()` doesn't wipe autosave revisions. It has
 some logic to keep a max number of revisions if they are limited by a
 plugin. The default is `-1` (unlimited). Also note that this logic
 specifically bypasses (keeps) autosave revisions, even when they are over
 the max.

 The code that ''actually'' does this is in `edit-form-advanced.php` when
 the editor checks for autosaves. I guess this adds an extra step to the
 process too:

 * User opens the editor
   * Editor checks current autosaves: `GET
 /wp/v2/posts/{id}/revisions?revision_type=autosave`
     * If any autosaves exist newer than the last save, display restore
 button
     * If any other autosaves exist, delete them
   * Editor creates a new autosave: `POST
 /wp/v2/posts/{id}/revisions?revision_type=autosave`
