Take a look at https://github.com/code-423n4/2024-03-zksync/blob/4f0ba34f34a864c354c7e8c47643ed8f4a250e13/code/system-contracts/bootloader/bootloader.yul#L2315-L2320
And https://github.com/code-423n4/2024-03-zksync/blob/4f0ba34f34a864c354c7e8c47643ed8f4a250e13/code/system-contracts/bootloader/bootloader.yul#L1833-L1841
We can see that tehre is a trailing comma in the function call but this is an invalid syntax according to Yuls formal specification: https://docs.soliditylang.org/en/latest/yul.html#specification-of-yul
Another instance not related to isNotEnoughGasForPubdata can be seen here: https://github.com/code-423n4/2024-03-zksync/blob/4f0ba34f34a864c354c7e8c47643ed8f4a250e13/code/system-contracts/bootloader/bootloader.yul#L972-L977
Borderline low this is cause the Bootloader.yul code would not compile with the correct Yul compiler. Even if it compiles with the current zkEVM implementation, it potentially necessitates an update to the Bootloader.yul code and its hash on Layer 1. Such an update would require a system upgrade.
Consider removing the trailing comma in both cases.
