I think this is a great method for reducing user interface complexity, by taking rarely useful things out of the main flow. Option-click is pretty much the only trick used for menus, and it's fairly universal across the nearly 80 years of Mac. The incidence of people that would be helped by those graphs, and the people that option-click is pretty high, so this seems like a great combination. It's similar to option-le…
The more I think about your points, the more I understand the whys. As someone who is moderately technical and new to macos, I wish there was a global "power user" setting.
You can get shockingly far just by holding the "Option" key while taking a lot of actions/looking at a lot of menus. Always the first thing I try.
