Oh good so I can completely ignore my textile industry? because I always get that up and running *way* too late.
Yes, most do not feel anything from being uncovered and the few who get embarrassed seems to have so little stress you can safely ignore it. I am 6 years in my nudist spire and everything was fine.
Adding food needs to something that do not get naturally hungry was a failure. They suffered the same problem as vampire dwarves, that is they get unfocused and never eat or drink. Besides, removing hunger makes the game really boring, so everything's back to normal. While you can run a fort on water, alcohol is better.
As it seems, building a
brothel tavern is very important. If the succubi do not get a place to socialize, they'll have terrible thoughts. Otherwise they'll romance quickly and argue to the point of going berserk (really, I had combat logs of succubi being enraged because Milith told Padaxe her mind). They did not fight each other out of spite yet but I think they behave in their own unique way now. I got a few humans and goblins visitors, by the way.
The biggest change is that they are a lot less lazy, or a least they always give up on break as soon as there is a job. It should be a the same for dwarves and as a whole it's less frustrating.
I still don't know what losing focus means, I had half of them blinking yellow without ill effects.
The next step is to change the pet setting. Without dfhack, they have no wagon puller and in 0.42 migrants are still entirely dependent on caravans.
As it seems, you still cannot tell a civ to settle on evil biomes so nightmares will still be cavern creatures (goblins already picked them up). Never mind, COMMON_DOMESTIC works as advertised, you can buy nashash, orthi, and nightmares and they all roam the surface of evil biomes.
