I don't see how this precludes just-in-time access. Even if people can re-up on their own, you can still observe the data access patterns and manage the risk. Further, when you see someone is getting blocked a lot you can improve the experience for them so they are unblocked, or have more efficient access to the data. This is just mature data and security management.

Quality of life and developer experience are important topics in many ways, but should they really trump security consistently? It's always going to be dependent on people's risk assessment and comfort, but frequently it skews the wrong way because the people making the decisions know that they'll be gone.
