Despite being very interested in Rust, this is the first I've heard of crev. It's a very cool project.

That said, it's interesting to me that several people are trying to get the project to drop the Web of Trust, and focus on code reviews. I'm the exact opposite - the code reviews are an interesting, experimental approach, but I'm interested in the project because of the cryptographic Web of Trust. Any use of dev-originated code signing in a package ecosystem is great. For this reason, I'd love for this to get major pickup from Rust, and beyond.

Finally, I am a bit wary because the project is starting to look moribund. It's important for projects like these to know that the maintainer is in it for the long haul, even if there's initially very little adoption. When the project founder writes that they're in a "fight for survival", it makes me think they may abandon the project if it doesn't get significant adoption.
