I
see this scrollbars as another solution in search of a problem to solve
and in the process introducing more problems than it solves. When will
people realize that this is not the right approach to do things.
The main advantage of the new scrollbars is that their real estate consumption is essentially 0. This may feel as a minor change when you're sitting in front of a 25" screen, but on my tiny notebook where every pixel counts, the improvement is significant. So yes, there are still some issues, but calling the scrollbars "another solution in search of a problem" appears quite unfair to me.
