I'm sure there will be more to come to this Thargoid war, but what and when is pretty much in the stars right now. Figuratively as much as literally.It might just be generic sorts of lines that they will use to explain how post-war tech changes mean colonisation is now something carried out by players rather than by Super Powers.
Personally when I read that I was expecting new 'Thargoid PP and PD' unlocks, as lots of AX ship possibilities are limited more by the power requirements than the other factors of the ship build, but unless there is a planned 'Phase 2' to the war I agree that would be of limited utility, and not of huge interest outside of a week's CG amusement.
We've also waited long enough for the Titan salvage CG to be kicked off, really. It was first hinted at... idk, maybe it was around the time that Thor went? I can't remember.
