Why use a green filter

I am just starting my mono journey along with Pixinsight. I noticed a lot of tutorials show how to use SCNR to remove the colour green from images. One site mentions that there is no green in space so it makes sense to reduce that colour much as possible in images.



If this is the case, then why bother to take images using a green filter (LRGB) in the first place? People still do so there must be a reason - does anyone know what that is?
