Proposals afoot are for the elimination of the unprovable ballot, not the full secret ballot. In such proposals, voters get to take home a receipt, which has a magic number on it, and the published ballots have this magic number, so one can go and look and see your ballot, with appropriate number, in the published list an be sure your vote was counted as you meant it to.

However, this does not reveal to anybody else, unless you choose, which ballot was yours, and you can destroy the receipt so nobody can ever learn. As such, somebody trying to challenge the eligibility of voters can't have that alter the results of the published ballots.
