Comment (by mattheu):

 I think you're right that this is only intended to be used internally.
 Probably lucky it worked as much as it did.

 The use case here is that I have a small plugin for meta & taxonomy
 revisions. This data may be a string or array. I did look at your patch on
 #20564 and my plugin is somewhat based on this. I'll comment on that
 ticket separately with feedback.

 I guess the real problem I ran into was to get my meta revisions show in
 the revisions UI. Thinking about it a bit more - I think that a better
 solution would be to make the value returned by `wp_get_revision_ui_diff`
 filterable.

 A separate issue is the triggering of autosaves/revisions for meta
 changes. This actually happens in a few places, and again a better
 solution might be an action/filter that could be used to handle this.

 I would love to see something like this in core - and I think that pushing
 for better hooks that allow for a solid plugin solution would be a good
 way forward.
