It is indeed true that arguing about complexity, while estimating, is useful to spark conversations about the item at hand. I feel that _estimations_ per se are not a good way to achieve those interesting conversations. You can, for example, analyze those items using the cynefin framework.

The tricky thing about estimations is that, for some people, they end up being a promise that then is used to plan the future leading, in some cases, to an unpleasant reality check.
