Eh I wouldn’t say enormously. The latter two are hyper powerful but hyper rare because how often is a newbie using threads? The former two are just a method call you add to the offending line when the borrow checker complains, and not a moment sooner. It tells you what’s wrong, you fix it, you move on. It’s no different than forgetting a semicolon in Java. Nothing needs to be undone after. Either those 4 tools get you a valid program or you made a logic mistake you would’ve made in any other language. Or in Rust sans borrow checker. I don’t see how that’s an issue. I don’t see how my methods are spurious objections or how I’ve spuriously objected to anything. My methods are tested, tried, and proven to work on a sample of n=1. All that’s left is government funding and we can start mass human trials next month.
