Thanks for noting the connection to Kant; ADT's minimally-metaphysical yet deontological approach, i.e. its Kantian approach, is its hallmark and triumph. (TDT goes heavier on the metaphysics and is weaker for it.)

It's a funny sort of deontology that is justified by the agent's preferences over its consequences ...

That's true, it is a funny sort of deontology.

Note that Kant actually claimed that he was not preferring one consequence over another, he was finding a self-contradiction in one consequence, and no self-contradiction in the other.

That is, "you should not steal" because, at the end of the slippery slope, there is a self-contradiction, something like "if everybody ought to steal, what does theft even mean?". (I'm trying to give Kant a fair shake, though I think he's wrong.)

I'm really not very familiar with Kant, but I guess I always thought to frame it like, after an infinity of time certain norms will defeat themselves, and other norms will reinforce themselves, and if we are to support a self-defeating norm then that's like choosing to become counterfactual. Then endorsing a self-defeating norm seems metaphysically but not phenomenologically possible, and since Kant didn't care about metaphysics, it's straight up impossible. Or something, agh. But anyway it looks ADT-esque, except that Kant had a hard time with meta levels for some reason.

I don't think it's right to say that Kant didn't care about metaphysics. Given that his work on ethics was Metaphysics of Morality and that was based on the more-metaphysical Groundwork for the Metaphysics of Morality. Whether one can choose a norm that is inconsistent, is a question for the noumenal world, not the phenomenal world.
