Good description.

One main advantage of SODA is that the laziest possible voter, the one who
just checks one candidate and goes home, has a vote which is essentially as
strategically powerful as any. Thus, I prefer delegation by default. But I
certainly wouldn't fight about it, and I'd happily embrace your version.

Exactly. In particular, it loses the ballot simplicity, and thus becomes
arguably worse than plurality in that way (ie, more rather than less
possible to unintentionally spoil a ballot in some way). Also, the
summability, and the complexity of strategic possibilities in the
delegation phase (although not, I think, the outcome; but I'm not sure)
both suffer significantly.

Thank you.
