Ultimately, a lot of Rust's safety features (which I'd argue are desirable everywhere, regardless of performance) require the sort of precise tracking people complain about. And once you have that, you might as well use it to free memory too. The idea of "Rust but GC" is fundamentally nonsense, because for GC to make sense you'd first need to rip out so much of Rust's selling point to begin with. It mostly seems to come from a perspective of "But surely all this GC research must be good for something, right? Anything?", rather than a concrete idea of where the GC would actually help.
