Enable ListItem SystemUpdate via REST

Allow REST clients to update list items a la SystemUpdate. That is, REST clients should be able to update list item metadata without creating a new version and without affecting system columns like authors and timestamps. The same idea for CSOM was recently implemented and I'm puzzled why the REST API is always left behind.
The CSOM idea:

        Thinking about how this should work - update requests (POST) needs to indicate we want a SystemUpdate() for CREATE/MERGE/PUT/DELETE

        So, a new HTTP Header perhaps?
