Can we give users with sufficient rep (10k? 20k?) the currently moderator-only ability to merge questions?
Some times a question is closed as a duplicate but its answers provide valuable content that will be lost if the question gets deleted. Since 10ks have the ability to (vote to) delete questions, shouldn't they also get the ability to (vote to) merge them?
I think deletion is only warranted when the content adds no value to the site. This is often not the case with answers to duplicates, and merging the original question means we'd retain some good content. This could also have the same "popularity" threshold needed to delete stuff.
Update: I realize the current merging system could pose some problems to this, but it could be improved to accommodate this feature (eg: by allowing the reversal of a merge). This of course wouldn't be the first time the merge feature got revamped.
