After discussion the 'changes' toolbar in writer with the QA team in the IRC, it seemed that i'll be submitting a few bug/enhancement reports regarding the improvement of the tracking changes features, so this meta bug is to track those submissions, as well as any another track changes related bug reports.
OK :)
