+ - xml policy inforcement and bus activated services is broken?
+ - rework errno registration logic
+ - how can we make the xml enforcement for native clients unnecessary?
+ - kdbus: the kernel should not allow messages to be delivered that have a reply serial != 0, reply-expect unset, but no appropriate window
+ - kdbus: when we fake creds euid being (uint32_t) -1 is weirdly translated
+ - kdbus: timestamps on kernel's NameOwnerChanged messages?
+ - kdbus: busctl monitor message ordering is wildly out-of-order?
+ - kdbus' busnames.target should get pulled in by basic.target
+ - Ignore .busname units on classic D-Bus boots, systemd-resolved cannot be started on kdbus
+ without the active policy and should get a Wants=org.freedesktop.resolve1.busname to
+ pull-in the policy.
+ - port to sd-resolve for connecting to TCP dbus servers
+ - kdbus: maybe add controlling tty and ppid metadata fields
+ - see if we can introduce a new sd_bus_get_owner_machine_id() call to retrieve the machine ID of the machine of the bus itself
