Well, I think that the main reason for this failure is that despite being easy to grasp, this scheme doesn't really reflect the reality. It seems to be chosen arbitrarily.

(Frankly, I think that anything involving "specify every detail of your known dependencies" is dead on arrival from a practical standpoint: it's way too much work.)
That's not true. All this work can be automated — if you're the developer, you've certainly compiled the code yourself, and the compiler knows what was imported from other packages. The only problem is to make it save this information into a specific file.
