I think they meant "why?" as in "what reason do they have?", rather than "do there exist people who think that?". I don't really care what tool was used to generate my assembly, and the kind of Rust that will be written in a kernel context[0] will - I guarantee you - produce virtually identical assembly to C. [0] i.e. no standard library ('no_std'), no unwinding panics, no dynamically sized types, &c.
