My experience of this feature in the betas over the last few months (for Notifications) has been excellent. I used to have so many notifs I would just ignore them all, now I can quickly glance and see which groups of notifs I want to actually read. In most cases, the summary contains all the info I'd want.

If you glance at the notification to decide if something needs attention now or later, then read the mail(s) in full - that's something different entirely and not a problem I'd think.
