They made another Ultimate Alliance not too many years ago and she wasn't in. It has Cable though.
She's important to the relatively recent history of the comic book franchise but it's not like masses of people will clamor for her if she stops appearing alot.
I honestly think the same of Magik, and she is my probably in my top 5 "young characters".
Grand scheme of things, the A-List X-Men in terms of general awareness, are pretty much just the ones from the cartoon and I think people know Kwannonlocke. (If you showed the average person any other version of Betsy, they would be like "who the **** is that?". But they know Kwannonlocke's design.)
Saying Hope is A-List is like saying she is as recognizable as Rogue. Ain't no way.
I say this as someone who has come to appreciate Hope in her non-Jean related roles:
At one time Hope Summers was in a Si Spurrier book. And that was after not being around for a while even though she had just ended term as the editorial franchise-wide McGuffin.
I love Hope though. By far the best Summers character.
