If you work on a well-modularized codebase, with small and individual Go modules, or Rust crates or NPM packages or whatever you call them... you do not live in an alternate reality. You are doing essentially the same as I was describing because the package managers for those tools force you to express cross-dependencies explicitly in a separate "metadata file". You are just doing so via a different, language-specific tool. The problem appears when: 1. you have a significant number of people working on the project and 2. one of these "modules" has become too big internally where it's hard to make sense of its internal structure. Having a monorepo makes the problem even more likely. At that point, you'll probably want to start breaking up that gnarly module into pieces so that you can see its structure again, right?
