There's no definitive "Bitcoin team" - there's the developers, Bitcoin Core, but they can't decide to override a specific transaction as there are no third parties which have power over them (this is a huge part of the reason for Bitcoin's existence).
It can really be hard for reversals of payments even if done unintentionally or something not a big fault of our own. You are right, Bitcoin is not built for reversals just like what we can experienced in PayPal or similar payment gateway as they really have people working to serve their members. This is the reason why we have to be careful in sending our Bitcoins and we have to triple check if the address we are using is the one where the funds should be going. It would be a big headache and can mean saying goodbye to our funds.
