No we don't, because years ago we devised a spec for embedded dlopen() based weak dependencies in ELF binaries. systemd binaries use that comprehensively for everything they dlopen(), to the point that libsystemd-shared.so now declares a whopping 26 of them. All relevant package managers have since been updated to read this metadata, hence in this regard we have not regressed.
