WTO jurisdiction blocked

If we end up without a deal, we are often told we will trade on WTO rules. But currently the WTO court that resolves disputes is blocked. I have not seen any explanation how setting up new WTO trading is expected to work without the court. Trading that is already established is risky enough, but since they will have been running for some time most potential disputes are likely to resolved. But setting up a new one is trickier.

Trump seems perfectly happy to leave the court dysfunctional, so if he is re-elected we cannot assume it will be running over the initial year or two when we need to set up many of the agreements.
