It's intentional, for two reasons:

1) make sure that the daemon can start even if you messed up your libraries. 
If the system bus can't start, then your system is pretty much hosed. This 
also allows for systems to ship just dbus-daemon and no library if they have 
other non-libdus-1 bindings (like gdbus).

2) the daemon uses the private API from libdbus-1, which is not exported. It's 
simply not possible to link the daemon to the standard library.
