Indeed. I would rather all browsers just disable it by default with not even the popup asking if I want it. If I install a webapp as a PWA then maybe ask me. Otherwise? Website operators are on crack if they think I want them to be able to spam my desktop multiple times a day even months or years after I visited them!

Yep, if this feature was limited to the window in focus, then the API could make sense. The way it is now, I know all savvy users will just block it, and many of the non savvy ones will too... Complete waste of time to dedicate developer resources too over e.g. in-line toasts.

Sometimes (as in a chat app) I want the window to notify me when anything changes, so I don't have to sit and look at it.

Sure! Unfortunately I am not sure I’ve ever seen the api used for anything other than what I’d call spam. To the point where as soon as I’m prompted I’m finding that “block” button before even speculating what it’s supposedly for.
