For me personally it's not a requirement the snappy window.. Apple is a small walled garden. They don't have wide screens so most of the time one app on the screen is enough.
I have an old 27' iMac and it wasn't enough screen space for me to put xcode, terminal and browser next to each other.
So the most used mode was split screen mode with xcode and a simulator. But the "split full screen" mode is much better and professional than windows' snappy window feature.
Windows tiling still keeps you on the overall Desktop, while the split full screen is a separate Desktop altogether with no access to the other applications (without exiting fullscreen).
