This would be a nice thing to have, but watch out for race conditions (e.g. a
new connection appears just as dbus-daemon decides it's going to exit).
You'd probably need specific integration with the named mutex that D-Bus on
Windows uses for autolaunch.
https://bugs.freedesktop.org/show_bug.cgi?id=11454 is vaguely related.

Not currently, but if someone (you?) wrote it (and provided a convincing
explanation of how the race condition mentioned above was avoided), I'd be
happy to review it.
Ideally, you'd also want a way for connections to mark themselves as "daemon"
processes that don't prevent the dbus-daemon from exiting (so it exits when
it has no non-daemon connections).
