#17389 Target visibility scopes New discussion created by kaos Copied from the design doc: Background Monorepos can by definition house very large code bases. In order to maintain good architectural hygiene it is important to adhere to intermodule interfaces and protocols to avoid chaos and escalating maintenance. Use Case By implementing clear boundaries for modules to interact only via public interfaces, the inner workings of the modules can be kept private, avoiding intricate and complicated dependency patterns. The visibility field offers the ability in a declarative way to specify which modules may depend on a certain target. Motivation We want to support large projects promoting good systems design. The visibility feature will be a tool that helps with that. Feature request: #13393 pantsbuild/pants
