Yeaaaaaaah, I wasn't sure whether or not to put that somewhere or not, and eventually decided not. I devalued all env vars, which I would feel like I had to move up to get into the PATH. I love the path, and I do agree with you that is important for understanding how the system really works, and how you can add your own commands, but I guess I figure that's a good Shell 201. For someone who wants to start using it, and isn't sure what a grep is or why a cat is involved, I figure they're not yet primed to care where these things live on their disk.
But soon after, for sure! And obviously others can disagree with me.
