Yes, but I believe that results in a cost/benefit analysis. If there are readily available rust crates that do something you need, and the cost of a possible vulnerability is not huge, most projects might decide (right or wrong) that it is worth it. It's an interesting question why projects tend to make different decisions in different languages, but it does not necessarily mean that you have to make the same decisions.
My point is that if you put a very high emphasis on avoiding vulnerabilities, you can either write the code in C with no/limited dependencies (and still risk memory safety bugs), or write the code in Rust with no/limited dependencies and no/limited unsafe code, and get much stronger guarantees for the same/less effort.
Fair, you see the perspective from someone writing the software and it makes sense. But when I see it though the lenses of someone choosing software to run, I would rather choose a C program with potential memory bugs than a rust program with a lot of dependencies - because I am more scared about supply chain attacks than someone being able to exploit a memory bug. But then again, this obviously changes if the rust program has no dependencies.
