Notifications are necessary for many applications, they are not for traditional websites although sadly that doesn't stop them from requesting permission. Imo the notification feature really should require at least https, like many other intended-for-applications browser features like service worker and location. On mobile you could replace most native apps (twitter, facebook, mail etc) with a web app if they supported notifications and save gigabytes of space for stuff that actually needs to be native.
