It adds a parameter to the kernel boot line. That is not adding a repository. It is not doing what you claim it does.
I am not putting any pressure on you. If you don't want to use it, then don't.
I find it hugely useful, have been using it for about 10 years now on dozens of machines and hundreds of distros and OSes, and it's saved me not just hours but days and weeks of work, effort, and time wasted writing files to USB keys.
All I am asking you to do is not tell lies about it.
