Hello! This is my very first time posting on the forum

First and foremost, I just wanna say that I, like many many others, am a big fan of yours and your creation. Now, the questions:
On the development page and in some DF talks, you've mentioned that you're planning to add ships and other moving fortress parts to the game. My question is:
will boats and other vehicles be modular and customizable objects that the player can construct block-by-block, or rather fixed structures, that are simply big blueprints the player adds resources to until the desired building is finished (like the trade depot, for example)? You've also mentioned that you have plans to implement a society system into the game that reworks justice, economics, and culture.
Will the society system affect individual creature morals? For example, it is currently impossible for dwarfs to butcher sentient beings. Could a civilization of cannibalistic dwarfs that get mood buffs from doing the currently forbidden things be generated? Will these systems be flexible, or stay the same for the sake of preventing the possibility bad PR (from what I've read, the mermaid thing could be considered an example of this)? While both of these, if ever to happen, will come in a far far future, and are most likely subject to change, I'm still curious about your current plans/thoughts
