Unrelated, but IMO, the clients for iCloud Drive on both iOS and OS X are very poorly implemented. I used to have a 16 GB of iPhone that would magically go from 8GB of available storage to 0 despite me not downloading anything onto it. It turns out, if you have iCloud Drive enabled on iOS, it automatically downloads the entire content of your drive to your phone and in the settings app, it classifies it under the "other" so there was no way for me to figure out what was eating up all of my phone's storage. The mac client isn't any better, it sometimes utilizes 100% of CPU to sync a few files (bird process on OS X) with iCloud and there's no way of stopping the sync or slowing it down.
