No, and there's been a lot of confusion about that on this website.
They did cite Rust's safety as a motivating factor for the port. That doesn't imply trying to achieve that simultaneously with the language change — which is good, because that would be insane. (Or, if you prefer, even more insane.)
You cannot faithfully port a codebase to a new language while also radically re-architecting it. You have to choose.
They want the safety benefits of Rust going forward; i.e., after it's finished, when they then write new code in Rust.
Yeah, exactly. The typical approach is to do a mechanical translation such as with rust2c, that is full of unsafe, and then gradually refactor safety in.
And the first post is about the team working on the project, with about two and a half sentences on c2rust, and making it very clear they just started.
The newer posts go into detail about the rearchitecting that follows.
