   >  that's the approach we took with FeaturesImage. Most callers use 
metadataVersionOrThrow. The rare use cases that may call it before it's set 
call the version that returns Optional and keep retrying until it's set (which 
is the desired behavior - it's not safe for them to proceed until then).
   
   I think it includes following changes.
   
   1. remove `metadataVersion` from `FeatureControlManager` constructor, since 
the `TimelineObject<MetadataVersion>` will be changed to 
`TimelineObject<Optional<MetadataVersion>>`. And it is initialized with 
`Optional.empty`
   2. `FeatureControlManager#metadataVersion` should be changed to 
`metadataVersionOrThrow`, similar to `FeaturesImage`
   3. `CompleteActivationEvent` should NOT use 
`FeatureControlManager#metadataVersionOrThrow`if the log is empty, since the 
`FeatureControlManager` has not yet set the MV.
   
   If above list is correct, maybe we can address it in follow-up?
