All our binaries now contain an ELF "note" that can be processes in a similar way as regular ELF dependencies. The format of these notes is described here: github.com/systemd/systemd/blob/main/docs/ELF_DLOPEN_METADATA.md There's now work ongoing to process this data automatically at rpm and dpkg build time, so that we get the best of both worlds: "weak" dependencies and proper metadata to declare them consistently.
