Fundamentally, it's an exotic form of mercenary - you hire them to do nasty things to other people. Sometimes you'll make do with a dozen or so hired guns from Footfall… sometimes you want the brute muscle of an Ork freebooter (a creature which lives for violence, and typically doesn't have much patience), the feral cunning of a Kroot (a creature for whom devouring the flesh of the fallen is a sacred act) or the merciless precision of the Dark Eldar.
Very true, but I just find it a lot harder to make a Dark Eldar "fit". Kroot are easy, as long as you disregard their distasteful eating habits they're loyal, pragmatic and completely unbiased, so they're perfect mercenaries. Orks are volatile, but at least they tend to be simple and unsubtle so at least you know where they're coming from and will remain loyal as long as you perform regular shows of force. But the Dark Eldar has personal habits more distasteful than the Kroot's, is almost as volatile than the Ork and is assured to be inherently disloyal. And worst of all, unlike the former, the Dark Eldar plots.

The crew don't have a say in the matter.
The rules for mutiny say otherwise

And the key point here is "if it thinks it can get away with it". One lone warrior against a starship crew is not the kind of odds a self-serving murderer-for-hire is likely to embrace.
Like you pointed out yourself, Dark Eldar are cunning and patient, so it will obviously not try to backstab him when he is in a position of strength surrounded by subordinates. He'll wait until he's weak, vulnerable and/or distracted. Perhaps when the rivals the Xenos sold him to are storming his house. As the saying goes "Fear the wrath of a patient man".

And if you don't want them in your game, don't allow them. Just because you're not sold on the idea doesn't mean that others won't jump at the opportunity.
That's beyond the point. I see no reason why such a thing should prevent debate on the matter. But the thing is I'm personally amazed that so much effort is dedicated to what I initially believed to be a niche class. I specially find it odd that playable Dark Eldar appeared before regular Eldar, which carry their own amounts of baggage but at least understand the benefits of mutual cooperation.
DISCLAIMER: This is not Eldar fanboyism. Personally I despise the Eldar as a race, but I still find the whole matter odd regardless.
