Oh yes, I simplified the build deps problem too much. Still feels like a task that is ripe for machine automation. As written the proposal is effectively asking every maintainer to dep solve the build deps manually in their head to see if their pacakge is still needed by something. IMHO that is inevitably going to lead to mistakes and puts unnecessary burden on individual maintainers.
