Unfortunately there's disadvantages to this approach too -- Android/iOS tools no longer work because files appear to be missing, for example. Understanding what Android/iOS want from you is harder because the files aren't there so you can't just explore the files and find the comments we left explaining things. You could imagine a mode where you ask the files to appear, then edit them, then ask the unchanged files to be removed, but now there's extra steps, none of which are obvious to the developer, and it's easy to accidentally add or delete the wrong file (or make trivial changes that you don't need to save), etc.

I do wish something like this would exist, though.
