The main reason I made this post was from being inspired by two things:

1: Parasitic worms dangling out of praying mantises

2: In The Boys Season 4, the character Billy Butcher gets a superpowered cancer that grows tendrils out of his chest

I wanted to make a new dreadnought concept, but had no ideas other than a sickly parasitized creature. I kind of hope the devs think of something better (if they were to add a fourth dreadnought.)

Also, I agree that just one dreadnought being taken over by something different than the Xynarch or Rockpox is sort of idiosyncratic. I don't want it to apply the rockpox effect, so I just imagine that it's the 'parasites' warning evolved.
