FYI, this is from 2015 and was deprecated around rust v1.0 release. It's not a current issue.

Well, it's still true that mem::forget is safe, and Rust will almost certainly never change that. As noted in the blog post, this makes certain patterns unsound.

Only if your definition of soundness includes that leaks can never occur, which is not how Rust generally defines soundness. I think most Rust know that the language doesn’t prevent leaks at this point.

Maybe, but the comment I was responding to is not at all clear about what is deprecated and what is no longer an issue. Note, too, that the other top-level comment on the post is from someone who didn't realize that destructors can be missed.
