+ - see if we can drop more message validation on the sending side
+ - add API to clone sd_bus_message objects
+ - systemd-bus-proxyd needs to enforce good old XML policy
+ - upload minimal kdbus policy into the kernel at boot
+ - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
+ - longer term: priority inheritance
+ - check sender of response messages
+ - dbus spec updates:
+ - kdbus mapping
+ - NameLost/NameAcquired obsolete
+ - GVariant
+ - "const" properties (posted)
+ - path escaping
+ - port exit-on-idle logic to byebye ioctl
+ - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
+ - allow updating attach flags during runtime
+ - pid1: peek into activating message when activating a service
+ - test bloom filter generation indexes
+ - introduce sd_bus_emit_object_added()/sd_bus_emit_object_removed() that automatically includes the build-in interfaces in the list
+ - port to sd-resolve for connecting to TCP dbus servers
+ - constructors for bus messages should probably not be OK with a NULL bus pointer
+ - .busname units should not use get_user_creds()/get_cgroup_creds() but instead do NSS only in temporarily forked off child
+
+* sd-event
+ - allow multiple signal handlers per signal?
