I wouldn't be to sure of that.
Homebrew is one thing, piracy another.
Well the one dude said to me on Twitter you not even need Kernel for Backup Loader, it just make it easier. So I asume Backup could made faster if there would be a skilled Person who gonna do it.
I'd rather have homebrew, we don't need a backup loader.
For me it is the different way. Homebrew is mostly useless stuff, like Cheat Tools or Emulators which you can play on PC^^
