The Yautja thing never really bothered me. In the novels, the term gives them a sense of something greater. The predators in the books are elevated beyond the status of mere hunters or predators. There are memories, personalities, history, culture, tactics, motivations, etc. But for the movies, I prefer a straight-up predatory beast that just so happens to use technology to its advantage. It feels more alien, mysterious, and threatening. So I can enjoy both versions of the same creature in their own way. But I do believe that incorporating that particular term and all that comes with it into the films would be a negative thing. It would simply humanize them too much.
