The purpose of the 127.0.0.1 line added to /etc/hosts?

I am not experiencing any problem with XAMPP 1.8.2-6 on Amazon Linux. But I am making some changes to my /etc/hosts file and found this line:
Does anyone know the reason that the installer adds this line? What is its purpose, and does anything in XAMPP rely on its presence? The name ip-10-0-0-12 does match the private IP address (10.0.0.12) of the instance where I installed it, but that address would obviously change if I launched a new instance with XAMP installed on it. I'd like to delete the line, since it has no value to software that I'm aware of. Could that cause any problem? I haven't found any so far, but I'd like to avoid any future surprise.
