Potential story repeat?
Well to answer your question:
No
Or to a better extend: There are no indications Anet has plans to implement this.The feature has been requested some times but it doesn’t seems to be a huge amount off people who wants this. It also poses some issues with rewards (even the amount off experience you get from just killing all foes again and the fact that some stories can be akitten/botted without any decent report way of monitoring this.
So if Anet would consider doing this, it would take a lot off time to develop and it is not considered something you could expect in e.g. the next 6 months.
