After reading this page of posts, and considering my earlier idea, here's something a bit more. Like I said before, I'm still pretty much a novice and may not have the same understanding that other folks in this thread may have.
I remember reading
Stranger in a Strange Land, and the idea of the Martians' maturity process has some stuff in common with AI War, and possibly with these hybrids. I read this a while ago, so maybe I'm a bit foggy on a lot of the details.
Younger Martians are nymph-like. They are small, impulsive, move and think and feel very very quickly. IIRC, they also die by the thousands and have a short lifespan.
Those Martians who mature long enough grow to an enormous size, and become slow, thoughtful, and ponderous. They live for thousands of years.
This is already a bit of a parallel here between the Neinzul and the Remnant. Still, I see a use here for Hybrids.
I said before, that I like the idea of Hybrids having the appearance of being impulsive. They seem to "blunder" into my territory on their way to a muster point, or a small group of them might appear to impulsively attack me in blatant ignorance of firepower ratings. Raptors testing the fence, or as the
War Nerd would say, "weasels who stand on their hind legs sometimes."
Later on, I've been swamped by much more powerful hybrids who seemed content to wait. In a way, these "patient" models built up much stronger modules, bode their time, and attacked when they were more "mature."
Bugs these might be, but until I read this thread, I saw this as a form of personality, a unique behavior. I wouldn't ever advocate keeping a bug in for flavor, only to spoil gameplay, but I hope this feature of hybrids somehow stays in, in a more deliberate form.
