I didn't attribute it to malice, I said that the OP's post is correct that Christoph's stance is hardline and a complete showstopper for the R4L project. His reasoning is likely one of pragmatism, by the sounds of it, and it's reasonable, but I simply don't agree given Rust's history as a language used in a codebase historically using another language (Firefox). The success stories there are already written, the language has developed with that in mind already. He's not being ridiculous or malicious, he's just being conservative and playing it safe, but that still gets in the way.
