I totally missed this bug report, however, I have opened a new one at
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1682484

Good news, is the fix for this issue is now in zesty-proposed. I have
verified that it fixes above problem. (No new / additional
NetworkManager or gnome-session-binary spam in kern.log)

** Changed in: systemd (Ubuntu)

Title:
  journald forwards to syslog with facility=KERN on everything

Status in systemd:
  Fix Released
Status in systemd package in Ubuntu:
  Fix Committed
Status in systemd package in Debian:
  Confirmed

Bug description:
  NetworkManager's copious syslog output is for some reason making its
  way into my /var/log/kern.log file. This includes a couple dozen
  <info> lines at startup and a similar amount when connecting to WiFi
  with DHCP.

  The NM man page states that the default facility should be DAEMON, as
  does the NM wiki -- see
  http://manpages.ubuntu.com/manpages/xenial/man8/NetworkManager.8.html
  and https://wiki.gnome.org/Projects/NetworkManager/Debugging

  Hopefully, it goes without saying that the KERN facility is reserved
  for the kernel and shouldn't be messed with by anything from userland.

  Nothing in the rsyslog configs references kern.log except the one expected line:
  /etc/rsyslog.d/50-default.conf:kern.*				-/var/log/kern.log

  Nothing in NetworkManager.conf references syslog or its facilities.
  Oh, and these messages do also correctly make it to syslog.log. I've
  no idea how or why they also end up in kern.log, though.

  This doesn't happen on Ubuntu 14.04:
  % zgrep -cv kernel: /var/log/kern.log*         
  /var/log/kern.log:0
  /var/log/kern.log.1:0
  /var/log/kern.log.2.gz:0
  /var/log/kern.log.3.gz:0
  /var/log/kern.log.4.gz:0

  On Ubuntu 16.04.1, NM is the major culprit, although there were also a few lines from gnome-session:
  % zgrep -cv kernel: /mnt/var/log/kern.log*
  /mnt/var/log/kern.log:402
  /mnt/var/log/kern.log.1:722
  % zgrep -v kernel: /mnt/var/log/kern.log* | grep -vc NetworkManager
  17
  % zgrep -v kernel: /mnt/var/log/kern.log* | fgrep -cve NetworkManager -e 'gnome-session-binary'
