> Scrum dogma is that estimates are for complexity, not effort or timing
The theory of story points (which originate outside of Scrum and are not part of Scrum proper) is that task-specific time estimates in creative intellectual work are extraordinarily unreliable and expending more effort on them doesn't improve them, but broad-banded complexity class evaluation mixed with empirical observation of the teams velocity produces time estimates that are (while still extremely fuzzy) both better and much lower effort, once you have the basic tracking in place, than task-specific direct estimates.
The “dogma” you report seems like something that might be a derivative of that that has lost track of rationale and purpose, reducing it to a cargo cult practice.
