Annoys me that "modern" in this case means whatever Microsoft does and whatever Microsoft users are used to. Especially since a lot of those "modern" binding have been around since the 80s.
"Modern" has become one of those words that's way over used to the point of meaninglessness.
Those keybindings are prevalent outside of windows though, Ctrl+C is almost universally copy and Ctrl+V is almost universally paste - it might have been popularised by windows at some point in history but it's well beyond that.
There's an argument for consistency, especially with basic functions.
