Take a look at the gas cost for ecrecover https://github.com/code-423n4/2024-03-zksync/blob/4f0ba34f34a864c354c7e8c47643ed8f4a250e13/code/system-contracts/contracts/precompiles/Ecrecover.yul#L22-L25
Its been massively increased to more than 6x its former cost of 1112, would be key to note that the execution of this contract is still the same without any execessive additional hashing/compiling that justifies this addition.
Users are now charged >6x the charges to ECRECOVER where as there are no real stand out addition in executional costs.
Consider reducing this cost or always attach extensive documentation whenever an update happens to a variable, especially the ones attached to costs.
