Not being able to have another app fix issues in the stock app is a problem.
If dropbox were able to express an intent to be notified of all photos taken, they could have solved this problem long ago and roughly as well, but they couldn't and so didn't. The problem is not that Apple solved this problem, but that no one else could have due to how apple treats all non-apple apps as second class citizens.
I'm glad Apple's improving their software offerings, because not everything of theirs is "works like it should" good.
