A lot of these don't need skeuomorphism to be solved. It just needs clearer designs. Always showing vital elements like the scrollbar isn't a skeuomorphic choice, it's always a good idea, they only started hiding them because it looked 'cleaner' to some UI designer. The same with using color to show window focus, separate distinct elements or foreground from background. Nowadays everything is just white, but this is just a product of visual design trends, not (anti)skeuomorphism.

Absolutely. I keep falling into these traps. I just got a Mac, and it's terrible at these. It's notorious for hiding the scrollbar, but why would they make it hard to find the thing I just downloaded? Or a screenshot I just took? I can open it, but that doesn't take me to the file location so I can actually do something with it. Although Steam is by far the worst at that.

It's almost as if we didn't learn anything about UX in the past 30 years.

Yeah, those are all legit gripes about modern operating system UX, but none of them are automatically fixed with skeuomorphism, and none of them couldn't be fixed with clearer design regardless of approach.

Used to be a solved problem before some ** messed it up. I hate that game too.

- Should there even be a scrollbar?

Many apps present content in such a way that makes it impossible to tell if there is anything more on the screen until you actually try to scroll. The home screen of the app is so clean and so fitted that there is nothing poking out from the bottom.
