When you have a street name changed, HN numbers don't need to be modified.
When you have a street with many RPP, you have to change the street name in each RPP, one by one.
This is also the argument of some publishers who do not want to use residential

It should be interesting to be able to select many RPP of the same street (with the control key for exemple or an option on the segment) to be able to change the street name in one time and in each RPP.
