At the moment many feature classes lack of the mustExecute() method and thus can cause a touched feature not to be recomputed and causes the feature to be in a broken state. Now this new enum value virtually makes the mustExecute() superfluous and thus guarantees to recompute a feature if a modified property has not set the Prop_NoRecompute flag. On the other hand there are properties that should only touch a feature but not enforce a recompute. This guarantees a better performance and avoids unnecessary recomputes. For example this is useful for placements where a change can be applied on-the-fly and the feature is up-to-date. Other features that depend on the touched feature will still be recomputed.
