What’s “safety” here? I don’t intend the question to be trolling. What’s the risk of bringing back a wooly mammoth?

Sure it could die of a weird disease bc we didn’t have the full genetic code. And yeah I’m equally unconvinced from the article that we actually can do this, but it’s unclear to me what the risks are if we can and do?

Scenario: Bring back one to one hundred wooly mammoths and… X worst case scenario happens. What’s X in your view for the wooly mammoth? I can’t think of any that seem actually bad but maybe my creativity is lacking?
