Unreal Engine 4 is available for Win10 UWP app dev now

Can someone confirm if I use Unreal version 4.19 and using the most updated UWP build in the fork if its possible to create a game and publish in the Creators Program without problems ? Other things like saving the game can be done using UGameplayStatics::CreateSaveGameObject as well ? Just don´t know how limited is UWP when doing those essential things to create a game.
