I really like the new installation language page…

I really like the new installation language page in coming WordPress 4.0, but I am not sure what is the main point of it? I am writing article for our users and I am not sure about it. There will be special localized installation packages as in the past (automatically generated), so when user downloads localized version, he usually wants to install this version. So, for 99,9 % users is this new page only some more bothering clicks? Or is there any other purpose? I know that I can download original English version and install WordPress in localized version, but it is edge case. Any ideas?
