Agreed. The inclusive-exclusive range is by far the most useful. There's unfortunately a massive case of lock-in here, but Scripture references would be ever so much more convenient as inc-exc. For instance, today in family devotions we read Galatians 2:1 - 2:21. At a glance, do you know whether that's the entire chapter? What if it were written as Galatians 2 to Galatians 3? Simple!
