The thing is that even `dylib` is just not very useful given the extent that monomorphized generic code is used in Rust "library" crates. You end up having to generate your binary code at the application level anyway, when all your generic types and functions are finally instantiated with their proper types. Which is also why it's similarly not sensible to split out a C-compatible API/ABI from just any random Rust library crate, which would otherwise be the "proper" solution here (avoiding the need to rebuild-the-world whenever the system rustc compiler changes).
