(A bit late to your comment, but I found it valuable:)
It's actually a classic bulshitting tactic by people who have no actual argument. Effectively, it's "well, we'll defer a choice until we can PROVE that decision X is PERFECT in EVERY way."
That's not to say: IF there's a real, quantifiable doubt, then by all means, continue to discuss (but preferably set time limits), but to do that you MUST set out precisely what the problems are, what potential solutions could (and couldn't) be, etc. etc. Not just vague "this feels wrong" objections.
