Yes there are Escort Destroyers in FSotSI, which is canon. I really think the differentiation lies in the type of vessel and the rest is best practise.I've been told that there is a 10,000T escort mentioned in FSotSI. Based on the quote above, I submit that an escort that size would be atypical. Which is fine by me, because I'm eager to minimize the damage done by the line that says that combat vessels include "some escorts". I think that to count as a combat vessel, an escort has to be atypically large and also that there aren't very many of those overlarge escorts.

The really culprit is probably CT:TCS. Spinal Mounted vessels would be something like, capital warships and everything else is an escort. We step back to the "age of sail". if you cannot stand on the line your an escort.
5 Sisters Tigresses a publicity stunt. I think not.
1. An advancement in a possibly dangerous sophont race is a good reason.
2. Making a statement to the Aslan and Zho would be a better reason.
If FSotSI is broken fine. I was looking at the MT: errata thread yesterday. I see that Rebellion ships we're fixed at some point, but SFotSI have yet to be touched after 10 years of the thread. I was never in the MT bandwagon (leaning more to TNE) but perhaps it's the best fallback version due to the errata. Still other than T20 we don't see a robust line of non-MT warships to fill those shipyards in Corridor.
