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!
