I think people has misconception of how works Direct3D 11. Nowadays, it just Direct3D 11 with 'feature level' : 9.1 (targeting Direct3D 9), 9.2, etc to 11.1 and 11.2). Thinks a bit like OpenGL 4.1, 4.2 etc..., just some 'extensions'

The thing is that you can write Direct3D 11 apps running on a Direct3D 9.0 hardware (minus the new features like geometry shader). A bit achievement from Direct3D 10 where only Direct3D 10 only worked for Geforce 8 or better (and AMD Radeon HD). Now it could works with very old hardware and still working on latest hardware/

Forward to Direct3D 11.1 from Windows 8: It added a couple of features that nobody really uses (3D stereoscopy) and now they added Direct3D 11.2 with tiled extensions (sounds for PowerVR or Adreno chipset for Windows RT tablets). On OpenGLES, it is called GL_QCOM_tiled_rendering. MS wanted to have that on DirectX, so they add to create a new profile '11.2'

The programmers were able to write Direct3D 11 games for 'Windows Store' and 'Windows Desktop' (for Vista or superior, using the 2010 SDK) as because and new 11.1 and 11.2 minor changes will be able available for 'Windows Store' because it also targets tablets and especially GPU that supports tiled rendering (PowerVR).:

So now, it is sure that DirectX new features are now exclusive for Windows Store apps, and there will be no more update of DirectX for apps targeting Windows Desktop (the SDK was not updated since 2010 for desktop).

DirectX for Windows Desktop (games for Steam etc..) is dead for 3 years already. It is now just an API for Windows Store apps . Also making a requirement to Direct3D 11.1 or 11.2 only games is stupid for a developer, since he probably want to support at least 9.1 profile

On PSP, some homebrew were so good that they went commercial
