If Mongoose were to say that they were going to re-introduce Virus, or one of the other setting wreckers, then I would be vocal in voicing my disapproval. Hop Drives (as Singularity explicitly makes very clear in two different notes to the GM, would totally rewrite the setting. That's exactly where people should let Mongoose know the risks that they would take. Fortunately, and unsurprisingly, Matt was quick to reassure us that nope, hop drives won't be something they use more widely.
Personally, I remain nervous that the Zhodani Expeditions book might use the other hilariously awful setting wrecker from that dark era of Traveller writing: the Empress Wave. It's way too late for me saying so to have any influence on a book that's already printed, and this is the first time I've mentioned it. But it if does show up, I'll chime in to express my disappointment and my hope that, in the words of Hume, it falls "dead-born from the press, without reaching such distinction, as even to excite a murmur among the zealots."
Also apologies: I missed the "not you" element. I admit that did rather take away the point of much of my post...
