We shouldn’t stop using /etc/sysctl.d for compatibility. I think the best way would be to create /etc/default/grub.d/40_sysctl.cfg with:
while read -r line; do
  if [ "$line" = "" ]; then
    continue
  fi
  if [[ "$line" =~ ^# ]]; then
    continue
  fi
  GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX sysctl.${line}"
done < /etc/sysctl.d/30_security-misc.conf
