I agree that cleaning /tmp and /run is a low-priority task, but what if there
are custom *.conf files in /etc/tmpfiles.d? AFAIU, these will not be run as
well, but may be needed.

And in the past, the difference in AC-powered and BAT-powered behavior in
pm-utils and Upower has created _lots_ of confusion.

Stock tmpfiles.d clean routine applies only to tmpfs (by default) filesystems.
On a battery-powered system, they are most likely clean due to small uptime.
