The runtime is the most interesting part to me. They are effectively replacing the LSB with a "binary LSB" that you can distribute with your game.
By ensuring any application compiled against the Steam Runtime will work on SteamOS, they are providing a solid baseline for developers. From now on, developers will know they can relay on Steam Runtime.
Next thing may be we start to see other applications (not games) to use the Steam Runtime and provide it on non-SteamOS distributions.
