But you also can't demonstrate that they are unambiguous for any possible
election method.

Doesn't matter. That's not the point of speaking of "intent."

Personally I don't have anything to add on these topics. I gave an
example of dealing with CR, and acknowledged that Approval is a weak
point.

> Aside from that, why is it ok to speak of intent, but not preference?

Intent is post-strategy. Here's an example of the process:

1. Say my "sincere preferences" are A>B>C>D>E.
2. Then I apply whatever reasoning and decide that I will be voting D>A>B
and truncate the rest. Then that D>A>B is my "intended vote."
3. At this point I the voter do not make any more decisions. Suppose the
ballot format is such that I can only vote for two candidates equally
and nobody else. Then my "cast ballot" is either D=A or D=B, according
to arbitrary resolution.

So an advantage of using intent over preference is that the voter only
has input at one stage. That's exactly as if you were only considering
cast ballots, except that you don't have to worry that perhaps the voter
was not allowed by the ballot to cast his preferred vote.

Preference and intent really take the same approach to not having to
worry about ballot restrictions, in that they both try to regard voter
input before it hits the paper.
