This touches on an open question and design challenge in the crypto field: - How to programmatically/formally measure/characterize decentralization ? - How to show the decentralization level of a particular dApp function execution to the user ?

That could be potentially very confusing and unexpected for a user if the WBTC redeeming process ultimately fell through, and they may come to blame other unrelated parts of the process.
