In fact, they are defined as people who can change the outcome of the war. Personally, I tend to think that the Vandenreich wants to recruit them, or at least, has to try to, so that they can guarantee the victory. Other than the main reason, utterly destroying the Seireitei, the first battle was fought in order for Yhwach to able to talk to Aizen. When Yhwach encountered Ichigo, he thought of beating him and then dragging him to Hueco Mundo to persuade him to fight alongside the Vandenreich. (I don't understand how he would be able to do that). We also saw Uryū recruited, without being named a Special War Power, in order for him to be kept under constant surveillance by the suspicious Stern Ritters. I'm positive he's one.

About other speculation, Orihime can bring back the dead, anyone would want her to be on his side. As for Ryūken, I believe that if Uryū is so special while being a Gemischt, what can be said about Ryūken? Him not having been appeared at all except for Memories in the Rain makes me think he will have a pivotal role, whether as a SWP or not.

I'm only speculating, and so, the one who misunderstands may as well be me, of course.
