Note that the first input argument, in the same pattern as previous versions of the L1 attributes transaction, is the function selector: the first four bytes of keccak256("setL1BlockValuesJovian()").

In the first L2 block after the Jovian activation block, the Jovian L1 attributes are used.

The pre-Jovian values are migrated over 1:1. Blocks after the Jovian activation block contain all pre-Jovian values 1:1, and also set daFootprintGasScalar to the value from the SystemConfig. If that value is 0, then a default of 600 is set.
