W11 also has an annoying snap behavior between monitors, which may have led to that decision. My left monitor is 720p and my main is 4K. On W10, I kept the monitors aligned at the top and it made it really easy to land on the bottom left corner of the main screen. Now it jumps up to the left monitor doing the same thing.
W11 by default centers all taskbar icons, including the start menu. You can change it thank goodness but the default is really dumb.
