There are still some features that a miss from Google photos. There isn't any way (that I know of) to auto add pictures to an album based on the face. I used to have dedicated albums for family members, and it was nice to have the auto updated.
Face recognition in general just isn't as good as Google Photos.
It's still an amazing piece of software and I'd never go back, but it isn't perfect yet.
The /people page looks a lot like albums based on face to me, is that not what you are talking about?
I'm waiting for that first point to. The good news is that they just started work on workflows, which should allow for that.
That's something that should be possible with the upcoming Workflow feature. Some details can be found in the November Recap blog post.
