Scrooge, I do recall that thread, and I found it: Thread:238917. This is a useful thread for this discussion.
By the way, I suppose my latter two examples are a bit tangential, but I wanted to clarify the types of references. For the sake of this thread, we should only consider the real world ones, but I thought looking at how we see the other types could help clarify.
Personally, I agree with CzechOut in his statements on that thread, and what is currently there at T:NO RW. We want to cover topics just how they are seen in the DWU, and the ambiguous real world connections have a place, just that they should stay in Behind the scenes sections. Just because it's in that section doesn't make it less important, it's just not clarified in-universe.
