Jungle Adventures was announced after that "polemic" rumor about the devs not wanting to include triggering content, so the devs were like "guess what, we are doing a game pack including danger next".
This is their definition of danger.
It wasn't really a surprise if you followed the news since the devs did say the sims would only die if you let them, that's The Sims 4 as a whole, needs to be shocked twice to die of electrocution, needs to stay in the fire forever to die...
In The Sims 3 your Sims could and would die if you were careless.
Remember the polemic about the whole "the telemetry told us" thing at the beginning of The Sims 4 life? one of the things "the telemetry told" to the devs was that, supposedly, most players played as a single Sim the whole time, some sort of avatar, so the devs focused more on this kind of gameplay for The Sims 4 (and well, since it was supposed to be a MMO at first, it's to be expected). This means no surprises because supposedly the playerbase found it annoying when their avatars died, nothing permanent ever happens without the player consenting, god forbid the player to be "annoyed" in any form whatsoever!
Jungle Adventures confirmed this is their philosophy now, avoid triggering the player at all costs even if the final experience is a bland forever-happy world, the rumor was real.
