You don't have to import anything to MS Word. Put your Word docs in OneDrive, it's free. You can open, edit, and save them from your OneDrive exactly like you would on a desktop computer.
Okay. Sure that's great for Word and Microsoft Apps but now you're suggesting I have to use three different cloud storage solutions and this still doesn't work for things like Pythonista or Nebo. Which is the exact problem I have with the current state of iOS.
And while sure, most of the time I have internet the automatic assumption that fast internet is available is something that's annoyed me across multiple devices, especially games consoles. The infrastructure in the United States is not good enough to make that assumption as far as I'm concerned, and where it is, it's usually handicapped with data limits.
