For most organisations traditional tools like IDEs, version control systems, logging and monitoring should indeed suffice. A great IDE such as IntelliJ IDEA and a tool like GitLab help a lot when it comes to keeping track of source code dependencies and deployments. Having a tool that visualises all dependencies in one place is nice to have but it shouldn't be essential to run a system. If you're running a larger number of services service discovery and properly naming services is vital rather than being able to visualise them.
