+* MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
+
+* "busctl status" works only as root on dbus1, since we cannot read
+ /proc/$PID/exe
+
+* systemctl: support --recursive for list-sockets, list-timers,
+ ... too, not just for list-units.
+
+* implement Distribute= in socket units to allow running multiple
+ service instances processing the listening socket, and open this up
+ for ReusePort=
+
+* socket units: support creating sockets in different namespace,
+ opening it up for JoinsNamespaceOf=. This would require to fork off
+ a tiny process that joins the namespace and creates/binds the socket
+ and passes this back to PID1 via SCM_RIGHTS. This also could be used
+ to allow Chown/chgrp on sockets without requiring NSS in PID 1.
+
+* New service property: maximum CPU and wallclock runtime for a service
+
+* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
+ $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
+ should SIGSTOP all unit processes in a loop until all processes of
+ it are fully stopped. This can later be used for app management by
+ desktop UIs such as gnome-shell to freeze apps that are not visible
+ on screen, not unlike how job control works on the shell
+
+* completions:
+ - busctl zsh completion is outdated
+ - systemd-nspawn -Z/-L/-q is missing for zsh
+ - manager property enumeration was broken when systemd moved to /usr/lib/
