S0 is a step forward. Disabling CPU entirely is just a "workaround". Both S3 and hibernation has a lot of security implications which S0 solves. Apple uses their own S0 alternative and it works... Perfectly?

The real problem is that both AMD and Intel S0 implementations are mediocre at best and this is what they should fix. Also most vendors are dickheads and cannot even verify that their system even goes to S0ix states without any problem before releasing it. Because of their laziness you can buy brand new certified "Linux ready" machine which won't even achieve S0ix states out of the box.

In other words, for the user, it's not a step forward. It doesn't matter if the spec is perfect.
