Not sure "convenience" alone should be the deciding factor when choosing a language for a project/product.

What matters more is the long-term value for what’s being built and maintained.

For portable, high-performance backends, Rust often offers a higher value/friction tradeoff, IMO.

For Apple platform development, Swift is the obvious choice.

Swift’s cross-platform story has improved, but outside the Apple ecosystem the incentives still seem weaker compared to Rust.

So overall, IMO, Rust tends to have a higher net value beyond Apple-specific use cases.
