IMO, we should all stop comparing software, as there will be neverending differences. Frankly speaking, Khaled has the rights to decide whether or not he wishes to release a bugfix for 6.03. If he feels that 6.12 should indeed be the "bugfix version" for 6.03, so be it. No point complaining and comparing any further. Khaled is the author! We don't get to tell M$ what to do either, do we?
