What’s the goal of the ValidationModel.Optimized? I see it being passed around here and there, and it seems to disable certain validators such as DependencyValidatorsFactory. But what’s the rationale behind it?
Some validations are expensive, e.g. everything that involves a call to the DB: Unique checks, assets and references. Therefore you can disable these checks for bulk updates. You also have not consider the insert order then when you insert self-referencing contents like menu items.
