That should be rare because if that case of yours is common, someone has already "safetify" (put in a safe interface) in a crate that you can pull in and use. Secondly, your time spending on "safetify" your unsafe code is just a trade off for time debugging safety issues in the future when you use your unsafe code in the future. Heck, Rust was born also to let people declare the way their "unsafe" code can be used in other to parallelize, because keeping all the unsafe contracts in your head (or even document) is not scalable.
