Apps would still appear in a system like this as soon as you have third-party developers, as a natural consequence of Conway’s law. And once you have that, there’s also security and principles like the rule of least power that motivate the current design which you haven’t gotten rid of.

As a matter of user experience, rather than implementation, the 'filesystem' in iOS is just an app. It's one way to handle data sharing and transfer between apps, but it isn't always the best, nor is it the main one.

This has some tradeoffs, everything does, but I'm glad someone is exploring the OS space without considering filesystems as we currently understand them to be an inevitable part of that.

I can imagine an object capabilities framework, in which a 'filesystem' is just an object which owns data, organizes it in the familiar way, and shares capabilities with other objects, being quite useful and powerful.
