And of Windows 7-8-10 (and of Unity). And the opposite is just copying the behavior of Windows 95-2000 (XP would already group taskbar buttons by default although it still couldn't "pin" them and required separate launcher buttons).
And, by the way, MacOS doesn't group all the windows by default, some get a separate icon when launched (at least they did some years ago, I don't know about the recent versions).

Fortunately, there are many different WMs/DEs on Linux and you don't have to use KDE (or its default set-up) either. You can either tweak it, or choose a different WM/DE or write your own (I would totally do so if I had more spare time).
