Perfect suggestion! Thank you!
I've just did a basic review: Add review for attohttpc v0.4.5 · dpc/crev-proofs@77cf6ac · GitHub and it looks exactly like what I was looking for.
Also, with all optional features disabled, it looks like almost all its dependencies are already reviewed by one of the cargo-crev users:
$ cargo crev c v --target --no-default-features --no-dev-dependencies
