Both of you say that a drive app is unnecessary, but i don't really understand how the workflow would be.
For example, today, i use my Google Drive as my main folder for my studies.
I have folders for the different courses, inside of those folders i have folders by subjects - Tests, Lecture Notes etc.
If what you're saying is the workflow expected from me to use, there is no way i would be able to use the iCloud drive as my main folder for anything other than maybe photos. There is no way i would be able to arrange anything with that confinement of opening iCloud drive saved files through their dedicated apps! For example, i don't want to open the Pages app on my iPhone or iPad and see all my Pages files from all the different courses i take. Even if i would hassle and arrange it somehow with an enormous duplication for every app, still, how am i supposed to remember that the specific test i am looking for was saved as a Pages file and not PDF...? Maybe a search inside of iCloud drive could have made things better, but not much better because there is no way i can remember the exact file name of every file i'm looking for.
They actually didn't improve anything other than giving more apps the ability to work with iCloud drive. that's just absurd. There is no way people would use it as their main folders for anything. They've totally missed it!
