Ah, the nitpicking contest. I know it well :( My solution is to bluntly and quickly ask for a likelihood estimation. If the nitpicker can't tell, they have to find out for the next discussion. Until then it is shelved. If it is below 80% it is shelved until it becomes more salient.

That led to a few interesting developments. 1) participants say their edge case and immediatly shelf it themselves. 2) Or, they come prepared with good reasoning why case X is important and must be treated now. Discussion itself became more constructive, too. In any case a win!
