That reminds me of something iOS is doing (though I don't know when it was introduced). An app wanted permission to my photos. In addition to the normal "Allow" and "Deny" options, I was also given the option to allow a subset of photos. I chose that option, and was given the normal photos UI, as if I was selecting a set of photos to share or delete. I guess in the back-end, iOS constructed a new photos library consisting of just the ones I selected. It was cool! And it's good to see things at least one of the things you describe is being shown to a large number of folks. Hopefully that'll drive momentum to wider adoption.
