Yeah I was thinking about this each time I had to fix it. ;)
In certain cases that is probably possible, in other cases, we want to distinguish which region gets called out. And there it uses the region name, which contains the line number. So, if we have multiple regions, we potentially want to make sure it is the correct one.

In any case, if you have ideas on how to address this, you are more then welcome to share them.
