I’m not completely sure what to do here because many crates seem to get published from the release PR branch, not the main one, so the commit id is usually unreliable anyway.
On one side I want something strict that can’t be easily bypassed, on the other if everything’s a red flag you’ll just ignore it
Hm, that is a fair point. Perhaps it would make sense to produce a table of checks: indicate which checks each dependency fails/passes, and then colour code them with severity.
Some experimentation on real world code is probably needed. I plan to try this tool on my own projects soon (after I manually verified that your crate match your git code (hah! Bootstrap problem), I already reviewed your code on github and it seemed to do what it claims).
