If I remember correctly, Valve from the start considered SteamOS as "backup", a way to escape Windows if MS pull some shenanigan they don't like.

Since MS is mostly "behaving" themselves, Valve is keeping SteamOS around, but not focusing on it.

At least for now... (it wouldn't surprise me if MS became more aggressive in their W10+DX12+"Xbox everywhere"+"MS Store" push...)
