Bitcoin Core already implements this safety limit with the "absurd fee"
limit of 10000 * the minimum relay fee. This limit is active in both the
wallet and the sendrawtransaction RPC call. Additionally for the wallet
there is a user configurable -maxtxfee option to limit fees set by the
wallet which currently defaults to 0.1 BTC.
