HDD spindown at shutdown as a default

I wondered if there is any good reason not to spin down the harddrives on the LibreElec shutdown/reboot ?

I followed hints found in the internet and:

1) installed "System Tools" add on (to get hd-idle)

2) I created a shutdown.sh script at /storage/.config with the following content:

#!/bin/sh

hd-idle -t sda

hd-idle -t sdb

hd-idle -t sdc

hd-idle -t sdd

and added executable permissions to the file:

chmod +x shutdown.sh

IMHO this could be a default behaviour.
