Rust isn't a language for a special case, Rust is universal. Those other languages are for special cases, you're simply a special case developer.

Picking a different language for each special case is the primary problem Rust solves, it's the problem of being a jack of all trades and a master of none.

>> If anything all those attempts prove that for many scenarios, it is better having automated resource management + (affine, linear, dependent, effects) than the pure affine types approach taken by Rust.

Can you write the proof down for us please? I'm curious, how do you prove that "for many scenarios" A+B is better than B+A?

The OP is about doing A in safe Rust, which isn't even an option for many of those other languages which are, at the very least, bootstrapped from unsafe code.
