  "why_use_this": "Install LLVM 20 alongside other major versions when you need a specific stable release for building clang, lldb, or other LLVM-based tools, or when your project pins a particular LLVM version. Keg-only to avoid conflicts with the default llvm formula. Commonly a build dependency for languages and toolchains that target LLVM IR."
