I think the main issue is that the Star Trek universe is filling in very quickly and people don't believe it is IMPOSSIBLY HUGE. I've always felt that there's nothing preventing Kirk or whoever from finding a vast Federation-sized entity right next to the Romulans no one has ever seen or heard of before because that's what space is like (at least in Star Trek).
Others are really annoyed at the fact Enterprise steamrolled around the Trek universe so the Klingons were found very early and so was virtually everyone else, which really confused a lot of people who expected space to be a great unknown. Nevermind the Vulcans sharing star charts.
Also, is she Bajoran? Are the Bajorans the only wrinkle-nose aliens?
