This service is for code artifacts. What credential to the developers use to access source code? Do they expire?
It is common for developers to use Git to store source code, in a hosted service like GitHub. It is common to use SSH keys to access Git. Frequently those SSH keys are generated without passphrases. Those are non-expiring credentials stored on disk. If HTTPS is used to access Git, it will likely be with non-expiring credentials.
I'm not saying short lived credential are bad, not at all. I'm pointing out how this service differs from similar services, requiring a change it workflow, which might be annoying to some people. Not everyone is operating under the same threat model.
