Components don't support conditional replication

There is no Prereplication method on ActorComponents. They also don’t appear to work with their owning actors IRepChangedPropertyTracker out of the box.
I’ve posted on answerhub as well here:https://answers.unrealengine.com/questions/162329/is-there-a-reason-prereplication-does-not-call-a-s.html.
This is a pretty big lack of a feature.
