While I agree with the sentiment of 2, there is a gap here: a lot of low-level Rust code is necessarily unsafe. In some areas, rewriting in Rust provides margin benefit - an unsafe block is little better than C, for example. We should be searching for targets that are not only critical, but not necessarily unsafe. That being said, any amount of unsafe that can be prevented is better than none.
