This comment is beyond uninformed. Rust is currently working towards standardization, starting with the memory model. See http://smallcultfollowing.com/babysteps/blog/2016/05/23/unsa... . This work is being undertaken by Niko Matsakis (a Mozilla employee, so yes, Mozilla cares about standardization) and Nicole Mazzuca (an independent volunteer, so yes, Rust takes broad input from the community).

As for "they want everybody to use it in their systems, and have no input on where the language should go", you appear to be utterly clueless about how Rust is developed. Enormous swaths of the language have been designed by contributors who just showed up out of the blue and started putting in elbow grease. Iterators. Every data structure in the stdlib. Crucial, fundamental details of how the borrow checker operates. There's an entire repository for allowing anyone to propose changes to the language (a process which Mozilla employees are also forced to follow), which is a model that several other open source projects have since adopted (e.g. Swift).

Huh? Anyone can submit an RFC: https://github.com/rust-lang/rfcs

While Mozilla may not be the best organization, the Rust team seems much more willing to listen to their users than the Firefox team.

Really? The Rust community has been one of the most open and encouraging ones I've seen. They've also taken great pains to make sure that community feedback is solicited and incorporated.

From the little research I have done into Rust it seems unsurprising that there isn't a formal definition as any Rust standard would be similar in value to Haskell 2010. Useful but not sufficient due to the language still evolving.
