With nightly builds, there’s more of a chance that a piece of malware could sneak in and get used to build a release of Libra. I’m sure the Rust maintainers would find it fairly quickly, but even within a few days there would be tons of Libra users with compromised wallets. More scrutiny goes into stable release builds than nightly builds, and more mature languages and tools have more experienced maintainers who are often (but of course, not always) better at scrutinizing releases. It’s not that MSVC++ can’t be compromised, but it’s pretty unlikely that it would be.
