Rust does not even have a specification, and stable release yet! You are lucky if current version, compiles two years old code!
Rust will be "repeatedly tried and tested" maybe in year 2040!

Rust has editions for strong stability guarantees, and has had them for nearly a decade i believe. Besides, tech backing has grown way past the risky point.
