      How do you vet and security check them all? Any process one can put in place scales badly with the number of dependencies.

      How do you vet and security check all the OS libraries you depend on? I think people like to complain about Cargo, NPM, etc. because they make the complexity of software very visible, when the real issue is just that software is complex.

      I come from the Python world which has significantly fewer dependencies do to the restrictions of the import system. There the total number of involved actors is much smaller and easier to audit.

      As an example every sentry dependency in Python is signed off now. Nobody is allowed to add a new one without sign-off.

      That seems like a pointless restriction, but OK.

      So if someone writes a homebrew implementation of AES-GCM, that doesn’t require signoff, but importing NaCl would? Seems like that policy makes security worse, not better!

      That’s not a realistic concern because nobody writes that. On the other hand we do specifically not allow the use of third party api libraries for things like slack or jira to ensure our network restriction system is used.

      People absolutely do write their own crypto code, with disastrous results. See Cryptocat.

      There’s no fundamental difference. Crypto just had to figure things out before the rest of the industry did, because the stakes are higher. Software is hard, and that’s why we need to converge on mature well-tested implementations of things instead of rewriting forever.
