> But it’s not a panacea, and the footprint of `unsafe` buried in so many crates is worrisome, especially when novice systems programmers see “guaranteed safety” and make assumptions that aren’t necessarily valid.

On top of the tens of thousands of crates that (ab)use unsafe everywhere and programmers importing lots of packages and installing hundreds of transitive unsafe packages, using an NPM-style package manager and marketing this as "guaranteed safety" does sounds very much like the Rust hype-squad are over hyping their snake oil to push the cargo cult.
