Google's post says that, while notifications are "an essential capability for a wide range of applications," Chrome's permission pop-up is also "a common complaint" among users that "interrupt[s] the user's workflow and result[s] in a bad user experience." To address these complaints, Chrome 80 will introduce a quieter notification UI. Interestingly, Mozilla announced basically the same changes to Firefox recently.
The quieter UI will block notifications by default, rather than spawn a pop-up asking if users want to allow notifications or not. On the desktop, a message appears in the address bar saying "Notifications blocked," and clicking on the adjacent bell icon will allow the user to enable notifications. On mobile, there is still a pop-up, but it is less intrusive than before, being reduced to a single bar instead of a full-screen pop-up.
