Here's one thing I can say about eventual disclosure - it won't go easy! Not for the majority of the 8 billion humans on this planet.
But, does that really matter?
After all, 2nd worst case scenario is that the Death Traps haven't been dismantled, so when X number die, they come back to a world which has a whole new paradigm, so everyone will already know the real deal.
The worst case scenario is that someone(s) nuke the planet. However, from the perspective of an "is-be", this is largely irrelevant, cos you don't actually need a body! And, again, worst case - a new body in a new place. From the perspective of those awakened, they just go to wherever.
And, if the place is nuked, then there's a possibility the nicer guys upstairs will clean it up! (cos, at that point, their known existence means they'll be able to act openly).
(This all presumes that, upon full disclosure, they don't stop the nukes from going off.... however, I doubt they'll stop the religious loonies on the ground from making problems)
One other problem - how would most people on this planet know if they're facing a good guy or a bad guy? If I was a bad guy, I'd go for a limited disclosure now, pretending to be a good guy (which is what they've obviously already done for a while - but in secret). Remember - Lucifer was the most beautiful of angels (just using a recognised motif here...)
