This is literally the same logic they used to eliminate all the customization options in Windows Vista...the assumption that the standard user is too stupid to use those options properly, resulting in their confusion and frustration...so they just decided to remove them, instead.
Here's the next line of the same quote...
Baca continues: "We felt that providing a discoverable setting, just one right-click away, was a more intentional and predictable experience. It’s a deliberate design decision, not a missing capability."
If they're going to include a "discoverable setting, just one right-click away"...then they can easily make one of those settings a free-placement / lock function, in addition to some suggested presets. If they think it's easier to find those settings this way...then just put them there...don't remove them.
I will never understand Windows' obsession with "dumbing down" their products, rather than scaling up their functionality. Aside from the obvious explanation, "it's just easier for us to make it this way".
