The Xbox Wire post announcing the new Xbox app game aggregation only mentions that you'll be able to "launch games from Xbox, Game Pass, Battle.net, and other leading PC storefronts," initially leaving Steam with a big question mark beside it.

Microsoft is starting to test its new aggregated gaming library in its Xbox PC app on Windows. Xbox Insiders will now be able to see their Steam and Battle.net games all within the Xbox app — making it a single launcher for most installed PC games.

Microsoft's efforts to match Valve's SteamOS handheld gaming experience with the new Xbox app are great, but it may have a tough time moving me away from the Linux-based OS.
