Performance being important in system development is pretty much a given, and doesn't necessarily even need to be mentioned. You could argue that systems software is well defined as software where security, performance, and stability are more important than all other concerns. I think the fact that your comment didn't elaborate is why you're being downvoted, not for asking questions. It can be interpreted as a question, but it can also easily be interpreted as a shallow dismissal of their choice of Rust, which is a fairy common thing on HN. If you had laid out some details on why the choice puzzled you, your comment would probably have been interpreted more charitably.
