The ideal situation, for me, would be some kind of progressive disclosure or a way to toggle "Advanced" versions of these panels and sections but I totally get why Apple wouldn't want to do that. It's double the work for such a small crowd.
Progressive disclosure can work, but an “Advanced/Expert” type setting does not. Dunning-Kruger kicks in and everyone flips the advanced switch whether they should or not.
That doesn't mean it doesn't work. It just means that some people are going to overestimate their competence to make those changes. I would be happy if it could only be turned on via Terminal, for example.
