Demosaicing 16-bit images with VNG interpolation

Hi everyone, Everything is in the subject. Indeed, when I am reading the code of 'opencv/modules/imgproc/src/demosaicing.cpp', line 1492-1493, it seems that OpenCV does not handle 16-bit files for VNG interpolation.

CV_Assert( depth == CV_8U );
Bayer2RGB_VNG_8u(src, dst_, code);


Am I right ? Is this on the roadmap ?
