Installing SteamOS on a Zephyrus G14 2022 laptop (all AMD)

Hi! I'm considering switching from Windows to Steam OS on my all AMD Zephyrus laptop, which I believe should run quite well, but I have a few questions I'd be really happy if anyone here has answers! Or I just might have to try it out for myself.

The hardware combo of Ryzen 7 6900HS (with 680m igpu) and RX6700S should be great for SteamOS, right?

Is there to be an accessible "easy" Steam OS installer image available soon that isn't yet at the time of writing? Or will it just be installing the OS through Steam deck recovery media image? Simply, should I wait for some big release of the OS?

Steam deck's sleep mode is awesome while Windows is really horrible with sleep mode. Am I overly optimistic to think that Steam OS will give my laptop Steam deck's sleep mode super powers? And battery efficiency?

Thanks for reading!
