> Rust has a standard project layout, standard test runner, and a central code repository, which enables testing language releases against nearly all publicly available code (see "crater run").

I'm not sure why this is treated as a selling point. It helps projects up to a point, but the minute you want to do something that doesn't fit the mold, it makes things a lot harder. All of these products are orthogonal to a language, and yet they are very tightly bundled with the idea of using the Rust language. It certainly makes "business logic" systems and web backends easier to implement, but I'm not sure many people were building those in C++ to begin with (except in legacy systems, where you are stuck with what you have).

Also, I'm not sure how a language that is less than 10 years old (in its released, 1.x versions) has any claim to having no problems with evolution over the next 10 years.
