MacOS already does that. You're not going to drag a video file to the spreadsheet app icon with much success, but if the app knows how to handle it then it will work. I can't imagine using an OS these days that doesn't have that functionality.
I gotta say, I'm not a Windows user anymore, but it would drive me nuts if I couldn't do that.
Finder (the MacOS version of File Explorer on Windows) is an app you commonly interact with every day for several minutes. If it doesn't work well that's hours of your life you spend fighting the system instead of getting things done.
Those are the kinds of things that made me move away from Windows 10 years ago.
Again, not trying to disagree, just curious to understand.
