This could only have a _chance_ of working as intended if either 1) everyone was pinning and bundling from the same blessed set of binary artifacts, or 2) every such project's build output was bit-for-bit reproducible (and if no one ever used different compiler flags or versions).

I think it's safe to say that the real world is very far from achieving either scenario.

That's actually how Nix works (compiler flags and environment are also a part of the content's hash). Some newer languages like Go also have this baked into the module system.
