Tendermint: why GasWanted, GasUsed and Fee appear in in DeliverTx/CheckTx response?

Question

The ABCI specs declare that results of DeliverTx and CheckTx contain the following information:

...
GasWanted (int64): Amount of gas requested for transaction.
GasUsed (int64): Amount of gas consumed by transaction.
...
Fee (cmn.KI64Pair): Fee paid for the transaction.

I'm not sure why these parameters should appear in the response. How "actionable" are these to the Tendermint Core, if at all?

Feel free to ignore these for now. They are not used by Tendermint core.

Why not to kill these off all together then? – Max Levy May 31 '18 at 14:33
We may use them in the future to 1) order txs in the mempool 2) control execution – melekes Jun 01 '18 at 12:59
