Ask HN: Is observability over the dependencies in codebases still a problem?

Almost every codebase is calling a REST, gRPC, or a GraphQL API or using SDKs from an external or event internal provider. It gets harder to keep track of everything when the codebase matures and increases in size and from my experience sometimes it gets hard to respond to changes in time or even become aware that a dependency is deprecated and their API has changed completely. Do developers need better tools that to improve dependency and integration management?
