Yeah, it's useful for web.whatsapp.com, email, Slack. I appreciate that I can run these as browser tabs instead of having to explicitly install them as separate programs. The notification popup is useful for them. It'd be interesting if browsers had a default setting that didn't allow a site to ask for notifications until you had switched to the tab and left it open a handful of times, or if they expired notifications automatically after you hadn't been to a site for a few days. It would also be interesting if they only allowed them for "pinned" tabs.
