The only real ‘groundbreaking’ new feature (multiple desktops) was something that Linux had fifteen years ago.

what are you talking about? if you mean virtual as the others think, both linux and windows have had that for 20 years. if you mean something else I really really want to know.

anyway it also has better wsl (backported to 10 eventually), generally better performance and battery life, etc. it also had a mac dock that prevented me from doing the upgrade for 3 years lol.
