Looks like the RRG was maybe updated last week... kinda?

All the Armada docs have a posting date of 14 June 2018, and there is at least one change in the RRG: "A ship cannot equip more than one copy of the same upgrade card." was added to RRG pg 6 FLEET BUILDING bullet 5.

Oh, seems @svelok already did a lot of the legwork on this.

Probably part of the same effort with X-Wing and Legion were the mouse is loosing up publishing requirements. That's good news for everybody if it also helps with errata and FAQs.
