It doesn't ring hollow to me, it is goodbye in the sense it's the last time I get to see Harry Dean Stanton and Yaphet Kotto in the Alien roles, difference being with Sigourney Weaver's Ripley we have had four films so that's a reoccurring actor and character, and I didn't want Alien Resurrection to be the last time personally.
I found it fulfilling in a way that it ends with that message particularly, it felt like a reaffirmation of not only Alien's ending but Alien³'s as well, as that's the last time we really hear from Ripley.
I didn't think I wanted it, until I got it, much like that new facet to the Alien I also spoke of.
