{quote}Specifically, what stops the following from happening?{quote}
In this example, I believe (3) would not yield {{FOUND_INCOMPLETE_COMMIT}} but
{{FOUND_INCOMPLETE_ACCEPTED}} and so would correctly re-propose (2), expending
its ballot?
{quote}It seems the next prepare will return FOUND_INCOMPLETE_ACCEPTED and
trigger reproposal and commit{quote}
{{hasInProgressProposal}} first checks if {{latestAccepted.update.isEmpty()}}
and if so, returns false, i.e. this would not be considered an incomplete
proposal.

The fast read optimisation does however leave an incomplete _promise_ that we
might want to change to asynchronously send an empty proposal.
