For some issues unanimous agreement is already not needed. For example recently a law was passed in the Council with 20 of 27 votes (only with the help of an Austrian minister against the wish of her government).
Yes, I'm aware that unanimity is not currently always required. But a claim that the EU "is set" to remove a rule is discussing a change to the status-quo rules in this regard, which I haven't heard about except as a very much not unanimously agreed aspiration of some legislators and some member states.
