Except that conversation was actually a monologue which you haven't actually performed publicly yet. Rebasing private branches is like editing a speech before you give it: just common sense. If you restructured the "I Have a Dream" speech, you'd be hacking up history. If Martin Luther King Jr restructured the speech prior to August 28, 1963, as I am sure he did many times, history remains untarnished.
