Not to speak for VetteVet, but your friend, I believe, is right. I don't think anyone has said that this is a REQUIRED upgrade. It is simply HOW you run an internally regulated alternator, vs. the externally regulated ones that were stock on these trucks.

They still sell the external voltage regulators for these trucks....I've seen em in a catalog or online somewhere. And I guess they still sell alternators that are externally regulated. So you could restore your electrical in a way that is totally stock if you wanted to. But I think a lot of folks just want the cleaner install, and maybe a more powerful system if they have a lot of accessories (power windows, bags, etc..), and this thread and others like it are HOW you do that......if you WANT to.
