Ill tell from my world of react/rn/node/serverlerss - Many of my colleagues shared this concern as well - we can't have enough visualization on the codebases/states/data-flows.

There are three benefits - Understanding the codebase (even to plug in a new feature), Findings issues easier and I can't emphasize this enough - We can/need reach into newer complexities that we thought twice about maintainability. In summary, We can reduce threshold for developer expertise to onboard into complex codebases - freeing up, developers on the other side to tackle far greater problems.
