And fun fact: not only RHEL 7 and thus CentOS 7 does so, but too Debian 
9 and Ubuntu 16.04 LTS (I have no newer test install of that distro).

And frankly speaking, I don't see any indication that this violates with 
the FHS and that /var/run must persist reboots.

Can we please end this stupid discussion? Enough arguments have been 
exchanged to make clear that packages are broken if they ignore the fact 
that /var/run content is ephemeral.

Just the opposite, the FHS condones the CentOS arrangement.

Under /var/run it says:

  "In general, the requirements for /run shall also apply to /var/run.
   It is valid to implement /var/run as a symlink to /run."

Indeed, there are many UNIX ties Linux had that were severed by hard work
of developing systemd and friends. I guess we just have to live with that
(sigh).
