They are. You can replace the icon of any app straight in Finder, in the Get Info window. Copy the icon from somewhere else, click the icon in Get Into to select it, and Cmd+V to paste.
I mean, you'll need to get the original icon, but that's not too much work. I don't think Apple themselves should be shipping every high-resolution icon they've ever used for every app. OS's are already large enough.
I've attempted this for the brave browser, which has a horrible icon in my opinion. It works but the original one self-restores after some time, even without updating the app.
No, unfortunately it doesn't. I've also looked for a way to script this and came up empty handed. If somebody knows how to programmatically set a custom icon for an app or arbitrary file in macOS, please speak up.
