In RhodeCode we have a similar concept that we call diff ranges. It's not available in pull-request view directly, however, users can see this on a source repo if they select a range from changelog view. example: https://code.rhodecode.com/rhodecode-enterprise-ce/changeset/17d92eee8537026494f6d1560979e61e598e6aa8...f2a4f55df5d1a994bcdc33e557e3ba17af9e1b49 https://code.rhodecode.com/rhodecode-enterprise-ce/changeset... I agree with the concept and it's sometimes very important to see how each commit produced the final combined diff.
