Reminded me one benefit of email-based workflow.

If I started receiving email, that's usually because I'm in the right mood to doing so. In such mood, I'll be more focused because I expect nothing else to interrupt my work.

My problem with notification is that there's a pull towards clearing them as they show up. But there's no guarantee I have the right energy at the moment.

Also, I found that most notification systems on the web are poor mimics of what email client has already archived decades ago. Maybe the old folks really got it right for using emails.
