Hi,
I checked ACPI spec 5.0 and it states as below:
=========================================
7.3.2 \_PTS (Prepare To Sleep)
The _PTS control method is executed by the OS during the sleep
transition process for S1, S2, S3, S4, and for orderly S5 shutdown
...
=========================================
So it seems it is mandatory.
