Feature Request: SteamOS & Windows clients for hand held PCs

Would be fun to have a client for Windows and SteamOS/Linux so we can turn portable PCs like the Steam Deck and ASUS Rog Ally into clients for wired headsets llike the Valve Index and Vive headset to make them wireless without expensive specialized addons. All these handhelds are capable of in-home streaming either directly in Steam or through Moonlight/Sunshine and support hardware accelerated video decoding.
