Even if its not just "mutable" state there are a lot of undesirable situations for multiple package imports in rust: 1. Singletonish things like global allocators, rayon-core, etc 2. You may have made a package static safe to mutate with a mutex, but it could be a bad thing to have different versions of that mutex. 3. Compile time computed tables (unicode table, perfect hashes, etc) could be imported multiple times ballooning the binary. 4. ABI/type compatibility with any reexported types |
