Notification categories are like mailing lists now. You may have unsubscribed from the daily deals email but you're still going to be auto subscribed to every new slightly modified category in perpetuity. Unless you fully disable notifications for an app (in Android at least, in my experience), new enabled by default notification categories are added all the time.

I recently had to setup Microsoft Authenticator. It refused to register a code unless I enabled notifications.

You are a two factor app. I should never be in a situation where there is an unexpected login I need to verify.

> From my perspective, the more roadblocks the platforms put between unnecessary notifications and my phone, the better.

I know lots of apps behave badly when it comes to notifications but I'd still prefer if the apps controlled the level of notifications they sent. I could, of course, reduce that client-side, but I don't see why I'd want Google or Apple or any other intermediary see or control the notifications.

If an app behaves inappropriately, I could uninstall it. If a gatekeeper like Google or Apple prevent an app from sending me notifications, I'd have to change my OS, usually my hardware, too.
