Also - you have to sign code on Windows too! If you don't then Edge will try as hard as possible to stop the user opening it, and AV scanners can get very curious about what you're doing. Maybe Steam doesn't care if your game is signed? I didn't quite follow the logic around notarization either. Steam imposes more requirements and takes a slice of revenue! Notarization is a lot cheaper and faster than that. But I guess the idea is that Steam gives you features, whereas notarization is just a tax.
