Vendors have been using similar language to downplay potential bugs for decades, usually to disastrous results. At one point, even memory safety wasn't a big deal. I'm just waiting for a software package to have a security vulnerability when an attacker is able to trigger an untested Rust unwind path and put some Rust daemon into a state it didn't expect.

There are many good parts of Rust, but I don't think I'm ever going to convinced that the error handling wasn't a huge and unfixable mistake. It's because error handling is such a big mistake that Rust has grown layers of syntactic sugar --- try!, !, etc. --- to paper over the ugly spot in the language.
