I do think
cal888 was onto something several pages ago about "canon people" versus "story people" and their conflicting priorities. There's probably an interesting debate to be had about whether the overall world-building
is the story or just the backdrop for the stories.
And not just with regards to Star Trek.
I confess: back when I was a full-time editor at Tor Books, my heart would sink a little whenever a new submission would begin with several pages of maps, glossaries, geneologies, and a capsule history of the realm/universe going back umpteen generations. This didn't necessarily guarantee that the author was more into the world-building than the actual story, characters, prose style, etc, but it
was a red flag.
Even as I concede that this would not be a problem for a sizable segment of the SFF audience.
I guess that puts me over in the "story people" camp.
