I wonder whether it's the difference between the kind of fandom that does only have two many characters, whether it's Sherlock Holmes or Sentinel, and the kind that has other focuses of attention.
If everyone in the fandom is assuming the relationship, the nature of that relationship is probably the most important line to split along, whereas in a fandom like SG-1, where there are other characters and other possible pairings, the division is more likely to come between people who are interested in various different relationships.
