According to my teammate who actually wrote the C++ code for this, there are lack of documentations of how the AWS_MSK_IAM is supposed to work. He has to check the Java/Python implementation line by line to avoid those guesswork

Well, there's precedent for that since the $(aws eks get-token) is just a base64 pre-signed GetCallerIdentity URL but I don't think that's documented anywhere, either, but can be spotted by squinting at aws-iam-authenticator source

My suspicion is that if they didn't want to bother to write a C++ client, they for sure wouldn't have the empathy(?) to document how anyone else could, too. I said empathy but I kind of wonder if by publishing how something works they're committing to it, versus they're currently only one commit away from changing it in their clients, without having to notify anyone

That’s how it works when writing CDK outside of TypeScript. You have to review the TS docs to get anywhere.
