I'm wondering if there may be a configuration setting somewhere that I can change to suppress writing this output to syslog and write to another log file as prior to the upgrade it wasn't being written to syslog. I haven't noticed but apparently there's been no Xorg.0.log or Xorg.1.log since Aug of '16.

xorg xorg.conf
