Even if this was a genuine concern, they should still use Rust. Because it will be far easier to refactor the code that they ship into something that is safe and correct, compared to rewriting a Go codebase.
I'm not confident that average level developers are able to ship features in Rust as quickly as they would in Go, which is the root of my point. Those building tools, which generally do not have the same success metrics with respect to speed and correctness, should use the language with a focus on safety and correctness. Those whose positions do not lend themselves to safety and correctness should not use that tool.
