Dunno about other manufacturers, but Thinkpads removed S3. Stock BIOS on some T14 G3 had S3 had it, but it was removed by subsequent BIOS updates.

The notebook market is dead for me if the notebook can't sleep on 0.3% battery per hour and if it can't wake up within a second or so.

So far only macbooks and >5 years old Intel notebooks can.
