Oh, at first I was interpreting voting block as set of people with the same full preference profile. Obviously, since you are modifying RD, it should just be people with the same first choice, so my point doesn’t matter.
Unlike RD and ML, your proposal is not clone invarient.
I don’t like this because irrelevant alternatives can split a voting block, and have a large effect.
