I've already asked this regarding "Excalibur 16 AMD Ryzen 7 7840HS" and received answer - "
it has ACPI S3 support as an option in BIOS"
But in general and to keep track I think that is good to reflect this in specs as it is a thing that is dropped by many mainstream vendors but still desirable and a significant stopper for someone like me who still think that what was done is ideocratic decision that causes a lot of troubles.
So in general it will be good to explicitly say that it is still supported (and clients shouldn't bother with patching DSDT tables) and probably reflect in testing scenarios - like how long Notebook can be kept in Sleep mode, with S3 it should be predictable but with S0iX states probably not (up to completely compromised/unusable mode).
For me personally it is a great significant benefit in comparison with products from DELL/HP/etc
