Hellfire Assault, Hellfire High Council, Kormrok, Kilrogg Deadeye, Gorefiend, Shadow-Lord Iskar, and Tyrant Velhari (at minimum; I'm not sure about some others) have important adds involved in the fight.
Out of those, Kormrok is pretty bursty (though the tank hand has a decent amount of health), and Gorefiend adds might be too spread out to really take advantage of Shadow Nova. I can't say anything definitive about Hellfire Assault and Hellfire High Council, but with the latter, if you honestly think that having 3+ Black Arrows up at the same time (on potentially stacked targets?) doesn't sound pretty good, I don't know what to say.
Regarding the rest:
You can easily stay phased on Kilrogg long enough to consider it "sustained AoE" (~40 seconds), and it's extremely important to kill as many adds as possible. I could see BM being very good at this too; that just depends on tuning.
The add phases on Shadow-Lord are literally the entire fight (not in terms of duration, but in terms of importance). Every add phase involves ~5 trash adds and 1 -> 2 -> 3 important adds, increasing with each add phase. These phases last a nontrivial amount of time (again, 40+ seconds), potentially giving you time to build up Black Arrow on a few of the larger adds.
For Tyrant Velhari, I could see the argument that MM's 2T cleave would be superior, but it's still true that there are at least 2 targets up for the majority of the fight (since the first add is so useless we ended up having it alive even when the second add spawned).
As a side-note, one nice thing about the SV 2P/4P/trinket is that you don't really need to sacrifice any ST to AoE. If we imagine a scenario where there's a priority target (boss, important add) and some trash adds, BM would probably have to spend a lot of its focus just keeping Beast Cleave up. Since the Shadow Nova is tied to Explosive Shot and the BA reset is tied to Arcane Shot, you can pretty much fire out a multishot and continue your ST rotation, throwing out BAs as you get resets. Or you could go HAM with multi-shot and still get BA resets; whichever.
Maybe it's not clear what I mean by sustained AoE. I basically mean multidotting. You're right, SV's burst AoE will probably be shit with the AS/MS nerfs (unless the 4P is just godly and you pool a BA/LnL). There are plenty of fights with adds/bosses that will live long enough to get Black Arrow up on multiple targets, though.
Again, I'm not trying to say SV will be godlike, but a lot of the fights (in my opinion) fit pretty well with its tier bonuses and trinket bonus, so it *could* be depending on how things are tuned.
Sorry for the novel.
