Awaiting the poll and I will vote in it, but answering already.
I used to shoot RAW-equivalents only with my Fujifilm S3 Pro, Nikon D300 and Leica M8.
But since I started shooting the Ricoh GXR-M (with electronic EVF) I shoot RAW and JPEG combined, since it allows me to set the camera to B&W and I get a monochrome image in the finder and on the LCD. Which makes it much easier to find lights and darks in an image, it's like shooting the final image straight away. If I decide to keep the imported RAW file in color later, I still benefit from better exposed photographs since the balance between lights and darks is so much easier found while shooting.
And yes, I do discard the in-camera JPEG's altogether, having the RAW file and fine-tuning that later is much more versatile IMHO.
Not quite an answer that fits your question I think, but it's an answer...😉
EDIT: I chose the option that was closest...
I also do this with my NEX-7 so that I can see in B&W while I'm shooting and to have a quick file for preview--extremely useful. I usually discard the jpegs later in favor of tweaking the different tones in Photoshop with the B&W filter.
