Nobody else has ever complained about this.
I think that if you use NFS and not try to piggyback on user plex, you’ll be ok.
You can customize PMS to not run as user plex
example
[chuck@lizum ~.2002]$ cat /etc/systemd/system/plexmediaserver.service.d/override.conf
[Service]
Environment="PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/usb/plex"
User=chuck
Group=chuck
[chuck@lizum ~.2003]$
