Why is it important to use "depth_registered/points" topic instead of "depth/points" ?

[fettahyildizz]

I want to use this repo in project, however our project has other packages that use "depth/points" topic so I can't convert my camera launch files. Why is it important to use "depth_registered/points" topic? Is there something I can do with your code to make it possible?

Thanks in advance.
