You could use Rust editions to allow evolving the standard library, perhaps - they changed the prelude (slightly) in Rust 2021. That might come with its own problems - on the other hand, you can't actually tell the major version of any given library from code (unlike with Go), so changing the definition of a standard library package upon an edition change.
