I turned on Stage Manager around the time it was implemented in macOS, to try. I never turned it off. It has addressed pretty much every window management woe I had.
Furthermore, I am impressed how they nailed it from the first time: there were no changes since it came out that I noticed, nor would I want any.
There was a slight learning curve, you need to have a good mental model of how it works, but after a day I cannot imagine going back.
This may be the case. I worked on a website at work, but never really used the website. One day I was watching someone use it and noticed a bug. I asked the person if they had ever seen that before and they said all the time. I asked them why they didn't report it and they said that they knew we were busy and didn't want to bother us.
