Importance of planner's credit management

The planner could DOS the USDT OFT users but cannot steal or otherwise compromise any USDT.

The system relies on credits, which the planner is authorized to move across different chains. If the planner moves credits in a way such that a chain is left without any credits for other chains, then no OFTs may be transferred from that chain anymore.

This is an issue that the LayerZero Labs team is already aware of.
