G'day Chris Moreschi,
<snip stuff we've already agreed/>
But...sometimes you do get problems with WikiProjects at XfD, when Topic X may be important in Fictional Universe X but not in the big scary real world: then problems start. You tend to get discussion along the lines of "But it's a major robot in the 5th episode of the 3rd series!", when what you really want are discussions along the lines of "Can we demonstrate this has any major real-world significance?"
Usually Wikiprojects at XfD are a Good Thing, but there are limits.
Oh, absolutely: moderation in all things. (This applies to IAR/process BLP/completeness, professionalism/community, everything).
