Hi all, I have some concerns about the lack of diversity of contributions:
- most (all?) of the contributions used a distributed Rust toolchain, which suffers from the "trusting-trust" issue since they are self-compiled. I don't think I've seen any contributions using the mrustc build path. - there were very few contributions (two?) using the golang implementation - no attempt has been made to replicate the deterministic golang build - people did not capture the binary they used, so we can't do forensics in case of future questions - there were no contributions using alternative processor architectures (e.g. ARM64). I believe this is possible using the golang implementation. - there was a lot of focus on destroying toxic waste and not enough on the trustworthiness of the tools Lastly, the deadline was announce less than a week in advance, which makes it difficult to address the above issues.
