Just found an old post asking this, any news on this issue after 8 Months?
Using D3D11->DXGI->D3D10->OpenCL is not very handy, and setting up everything D3D10 only becomes outdated soon.
Is silence here an indication to choose Compute Shaders instead?
I don't know what the timetable is for DX11 interop, but in most cases if you're outputting to DX I'd recommend using compute shaders anyway. It's just more efficient to do it that way and performance is usually better.
