From my point of view I don't see anything wrong with knowing a little bit more about the person behind the app I'm trusting to do my personal compute on my personal device. Personally I always think twice when I download apps from company's whose names I don't recognize. Same with PCs... do you really want to run that *.exe you downloaded from that cool site you found?

Changes like this will help keep developers honest and accountable. Yeah yeah bad apples will still find ways to screw us.

If you want to publish an app to a global scale ecosystem, is it really too much to ask to give some ID?
