Is everybody that uses iCloud working on perfectly manageable one file projects? Im not. My projects have drafts, excel sheets, images, videos, PDFs, Word documents, etc. I need to keep those files together, as they are the project.
With iCloud I simply cannot do that. I have to distribute my project files over every single app I need to use to manipulate my project. As a trade-off, if I want to use iWork in the Cloud, I need to duplicate my files, edit/sync them, and then afterwards regroup them in a folder on my Mac. Its madness.
The biggest issue is that Apple forces its hidden-file idea on you without giving a choice. Offer it as a solution for newbies, for cooking recipes and party invitations, but for serious work, give us a file system. Its been around for 30+ years, theres nothing wrong with it.
Yep, Steve Jobs really screwed up when he started that ideology in Apple. He mistook the understanding required to use files, with the complexity of using a filesystem. Users want the ability to organise files in hierarchical structures - for most, they just don't want to learn about concepts like different file types (png, jpeg, tiff, bmp and on and on), permissions etc.
