There is no need for a side car file; we could have an extra section in the binary (ELF or other formats) in the same vein we have debug (e.g. dwarf) and other metadata.
Sure, it doesn't have to be sidecar (though as a sidecar you could add it next to existing binaries where you don't have upstream access as well and might be signed so you can't alter them).
