Here is proof that it is an intentionally-bad feature:
Web pages can tell if you enabled notifications.
The last time I checked, Slack used this to break unrelated functionality until you gave it browser notification permission, and re-broke itself if you disabled permissions after enabling them. Otherwise, there is no reason to enable it or install the app. (You can deny notifications per app, at least on apple platforms).
