Yes. Handing off IPC connections across a re-exec is a feature of
significant complexity, which will break the system if done wrong; it
would require support for serializing and deserializing dbus-daemon's
entire state (name ownership, connection credentials, the buffer of
partially-read messages on each connection, etc.) in a way that is
compatible across versions.

dbus-daemon has never had this feature, and will continue to not have
this feature until/unless someone implements it.

If you want to propose an implementation, I'd be happy to review a patch
series upstream (but I suspect it isn't actually feasible).
