Hi Martin, As far as my experience goes(which is less), the usage of SequencedEvents is relatively rare, and rarer even to generate a high volume of SequencedEvents. So, I would be inclined to pursue the path of blocking the dispatch till the SequencedEvents are processed. Probably Sergey/Phil are more qualified to comment on this, but this is my 2 cents!
