I don't like notifications. I never get any notifications requests, unless I'm in a private window trying because some site wouldn't work with adblockers etc. Life can be so simple.
I don't want your phone calls. Your conversation is not important enough that I'm willing to be interrupted by you. The lack of phone calls is a desired feature. Please stop using phone calls. If I want to talk to you I will write you a letter. You don't have to nudge me into it.
The problem with not implementing notifications is that when they are useful (instant dispatch software), they are not implemented. But honestly I’d just spin up a telegram or email bot, if clients were not brainwashed with tekhnology. Messages and email are notifications. It is also a matter of minutes, opposed to creating a stupid service worker client-server-like runtime and trying to get things right without any test mode (long story short, implementing and debugging webpush requires publishing every change to a certified https host). There is even an entire company that sells you a properly configured webpush as a service. That’s just stupid.
This would have made it possible to offer notifications without being in-your-face about it, which would have made them more amenable for sites that were concerned about brand image and user feedback. The paradigm might not have become unavoidably tainted, and we'd just name-and-shame the bad actors.
It also makes it clear that the notification consent shouldn't be a one-way street-- you should be able to discontinue notifications through the same UI and in an obvious manner, rather than treating it as a consent you can easily offer, but not easily retract.
