But this is only an optimisation, I think that would be equivalent to just
removing the condition and ternary operator entirely, and simply returning
{{latest(promised, latestWriteOrLowBound)}}?
i.e. on entry {{latestWriteOrLowBound >= promisedWrite}} so this is just a
single instruction short-circuit permitting us to avoid evaluating
{{Ballot#compareTo}}
