You'd still need a spec for this because of cross-language considerations, but that doesn't make it a bad idea.

i.e. if an app is written in javascript and running on mac there are potentially 4 different languages all running inside the executable that need to cooperate to handle the BOM signal and report their deps - C/ObjC, Swift, C++ and JS. Presumably you'd want to report not only the native libraries being used in the process but also things like npm packages.
