> BUILD files give you a chance to encode the high-level architecture of your software project as a graph of dependencies that lives outside of the code.

this is wild, the code literally defines dependency relationships at the mechanical level, it's the source of truth

of course you can't derive dep graphs from source code via simple file-based grep analysis, but that's obvious? you need to use language-specific semantically-aware tools to do that. if the author believes otherwise that's their mistake
