Stage3d on different targets

Hello there.
I wanted to ask about the stage3d API. I read that there is progress bringing it to the openfl but will it make a difference other than bringing accelerated graphics on flash target? Or would it be used differently on other targets as well, like rendering sprites to textures using hardware rendering?

We’re experimenting with render-to-texture by blending the BitmapData and Stage3D APIs slightly, you can also use the Stage3D API on all OpenGL-based targets (most desktop systems, WebGL, mobile)

Here is an example on HTML5:
