I get what you are saying (I really do). But, I can't think of a way for "deleted" photos to be saved for 30 days "in case" someone "accidentally" deleted it, without putting it into one of the Albums. I'm fairly certain that as a part of the staging for the movement of photos to iCloud Drive early next year, and the elimination of iPhoto as we know it, that basically, anything anywhere in your Photos app on any device signed into the same iCloud account is going to be sent to iCloud.
One of the upsides of this is that now, when you create your own little albums on your device, even if you don't set them up as "Shared" albums, they go to your Photo Stream on your Mac or computer. I just set up a new album, put some pics in it, and OMG - there it was in my Photo Stream on my Mac. So, I think that people will like that new feature. Thanks to your questions, I tried it and found out that cool little thing!
So, keep 'em coming John! This is new for all of us, so discovering the ins and outs is very helpful.
And thank you for bringing up the question about the Deleted Photos and Photo Stream. I also was not aware of that (hadn't thought about it, really), so finding out about what was up with that was very helpful.
I do get your point about the nude selfies (or whatever), however. If nothing else, it seems like after the fiasco a week ago, that we ALL should be getting a full explanation about how the "new" photos work, and what the basic steps are.... (maybe I should try to put together a User Tip) 🙂
