> And while I don't have enough experience with Rust to claim this first hand, my understanding is that writing correct unsafe Rust code is at least an order of magnitude harder than writing correct Zig code due to all of the properties/invariants that you have to preserve. So it comes with serious drawbacks, it's not just a quick "opt out of the safety for a bit" switch.

I think this is hard to generalize about. There are many instances where one might want to do unsafe memory operations in rust, with different correctness implications. I am suspicious that in Zig you do actually have to preserve all the same properties and invariants, and there's just nothing telling you if you did so or not or even what all of them are, so you don't know if your code is correct or not.
