Actually, the goal was to expose much requested desktop floating-point rendering functionality for WebGL 1.0. EXT_color_buffer_float (both the OES and WebGL versions) came later. If EXT_color_buffer_float can’t be implemented on D3D11, as implied by the above comment, we have a problem...

Olli raises a good point about RGB32F support. I agree with removing that support from WEBGL_color_buffer_float. When I wrote this extension, I was not aware that OpenGL ES 3 h/w would not have support for RGB32F.
