The SPDX generated information includes information about the generated binaries, the dependencies between them and also traces license headers used by a given binary through the binary debug information. Whilst it is true you could generate a simpler SPDX document without compiling anything, that isn't how our SPDX generation currently works, it includes a lot more information and some of that is from the binaries. You could create a different simpler spdx like class that could do what you describe but that isn't what we have today. We went for the version with all the information. Cheers, Richard
