Well, that's good. Now developers at least don't need to be held back by a 1.2 TF baseline if they don't want to.
Well...

Great thing is with Project Scorpio as part of #XboxOne family all your games will work, no Scorpio exclusives, so no one gets left behind
This is not true at all. Microsoft hid DX12 behind its Windows 10 platform and is hiding its games behind the UWP walled garden. That's not PC gaming at large and that's not exactly developing for PC. That's developing for UWP. Doom running on Vulkan as comfortably as is is a testament to how good it will be.
It will be available on ALL PCs, from older Windows to Linux. And yes, MS IS scared shitless of Vulkan because losing their API monopoly would completely FUCK them. They sat on their asses for a decade before going "oh we need to get our shit together wtf is this Mantle thing". They singlehandedly held back PC gaming for a decade. Vulkan is the future.
UWP is an attempt to make Windows relevant in a world where iOS and Android/Chrome are quickly becoming capable of being used for productivity. MS is merely leveraging XBox in an attempt to garner interest in the platform.
If you asked Nadella what he thought about SteamOS or Vulkan, he would likely say "What are those things?"
