Sounds like a good encoding to me. Taking the median of the three
options, and throwing away "don't care" votes entirely, makes sense.

And your proposal here fixes that shortcoming in a economically powerful way: miners lose out on fees if they don't represent the wishes of the users.

Thanks! I personally expect disaster to ensue with this kind of
proposal, but I'm less concerned if the disaster is something users
explicitly allowed to happen in a consensual way.
