The whole point it to give people options to get the feature they want.
I totally get that you prefer notification on your apps and no notification on the web, the same way people enjoy notifications on their watch and not on their phone, or only read their mail and calendar on their laptop and keep nothing on their phones, etc.
There is an infinite number of combinations of what people want, the whole purpose of these rulings is to let users manage the state they want instead of Apple dictating what is allowed or not solely based on their business interests, even if it those can align with your preferences for instance.
