I second this. If I thought I had time I would start one and moderate, but I know I would not be able to nurture it.
I would love this as well. It was a great community and I learned a lot over the years there.
I've been wishing for a lot of the text-based NSFW communities from the old site. Not only for discussions like the one you mentioned, but also the ones for stories. I hope that they will build up with time.
