I'm more incline that writers of the fluff for the three remaining (1st) WarShips had to explain what happened to the ships.
Given CGL's and many players bias towards the game balance of how WarShips have on universe is bias for mechs. Aka, they don't want them in the universe except in fluff.
Don't get me wrong, i love Mechs, i think their too heavy handed and causing them to be rare things and driven into extinction. That's why these three remaining ships are removed. If wasn't for the fact the Peregrine was mentioned in later years during the Wars of Reaving, all these ships would been toast.
I'm grateful for everyone who does does the Fanfiction stuff to keep them alive.
I'm actually little annoyed that most new new mini-TRO is filled with only Mechs, only ONE is actually a new new design.
