To be more precise, here's the workaround I scripted:

    if ! test -f /etc/X11/Xwrapper.config
    then
        apt-get install -y xserver-xorg-legacy
    fi
    if ! grep "needs_root_rights = yes" /etc/X11/Xwrapper.config
    then
        cat > lines.txt.tmp <<_EOF_
allowed_users = anybody
needs_root_rights = yes
_EOF_
        cat lines.txt.tmp >> /etc/X11/Xwrapper.config
    fi

I need that fragment in different situations, not just with
nvidia-370+ and startx, but also
with intel and amd drivers when running X servers inside lxc containers.
So I'm glad they left this escape hatch behind when they switched to
non-setuid X!
