> Now in the service of minimalism we have scrollbars that consist of a thin, semi-transparent line that fades out after half a second and is nearly impossible to click and drag due to how small it is.
You can make them always on still. I've done so ever since their disappearing act started. It's not even much hidden, it's in the "Appearance" setting pane.
They're still too small and too light. Some times when a document is big enough I'm actually not able to find the scroll thumb on macOS Sequoia. Some times wiggling the scroll thumb around by scrolling slightly back and forth with my mousewheel/trackpad helps to make it visually appear, but other times I just have to give up.
