My first caravan was husked immediately, in fact. Luckily I had boxed myself in before then, but it cost me in terms of migrants, due to the liaison.
I can't say I particularly like the insta-husking though. It's too RNG-dependent. Or rather, there's not much you can do to prepare for it (at least that's relatively short-term. If you roofed off the entire surface, I suspect it'd work. Or redirecting the caravan to the cavern, assuming that glitch still exists.). I don't mind corpses instantly causing fun, but the generic sudden death without save... meh.
Running through...
[X] - so inhospitable (weather/temperature) no animals visit the embark
[X] - all corpses instantly become undead, on the surface
[X] - next to 10+ necro towers
[X] - guaranteed dozens of megabeast/semi-megabeasts
Sure, to any of the above. Well, assuming it's possible to dig down before being killed.
[.] - no cave water, aquifer or surface water of any kind on the embark
...Maybe? I can see how you'd survive, but not really how you'd thrive... In particular, drinking water and dwarven footbaths, and obsidian (for later).
I'd be perfectly fine with hard-to-get water (cavern, a few tiles of aquifer, glacier, etc), and probably fine with a limited supply of water (muddy pools assuming it occasionally refills, etc) though.
[.] - no cave plants of any kind on the embark
Define "cave plants". If you include trees, see below. If you don't, and you start with seeds, sure. If you don't... maybe? Depends on the surface plants, and what you have access to.
[.] - no trees/plants of any kind on the embark
Plants, see above. Trees? Does that include caverns? If no, sure. If yes... maybe? It'd be "fun" to make enough beds, especially given that caravans are likely to die...
If you don't start with seeds... I'm not sure how you'd survive - mead (or water, although that causes other issues) and butchering I suppose. It'd be difficult considering some of the other things here.
Feel free to ignore any/all of the above.
