Could be a good idea. This more often that not feels like look what i had for dinner thread. A pic of your dinner does not translate as food photography in my opinion.
A pic of dinner is literally food photography, though. The source of conflict, I think, is the difference between "food photography" and "food photography." Those who come for the former don't want to see the latter. The two types share a thread because there wasn't always a dedicated food-photography forum.
I figured that navydoc's brinner photo was meant to be casual. If he'd wanted to emphasize the artistic side, he would have used a different plate, without such a distracting strong design.
Any suggestions for titling a spinoff thread, and which kind of photography shall be spun off?
