I would say that the multitasking stuff is not discoverable enough in some ways - but the tradeoff would be that for those who don't want complex multitasking exposing it more might make it more confusing.You're right, but they have done a good job of keeping it simple while making the multitasking more "discoverable."
If the rumors are true, I hope they can manage to maintain that trend.
I really really really hope they don't bring in macOS style multitasking... just fix external monitor support when you have a pointer and keyboard connected and then focus on the underlying structural issues and making better apps.
