README seems innaccurate - doesTxNeedFrontrunningProtection doesn't check gas > 42,000

The README, in this [section](https://github.com/flashbots/rpc-endpoint?tab=readme-ov-file#transaction-frontrunning-protection-evaluation-rules), says

> - Does the transaction use more than 42,000 gas? If it doesn't then the Flashbots Relay will reject it, and we're not aware of use cases that use such low gas that need frontrunning protection. Thus, we send low gas transactions to the mempool.

However, [doesTxNeedFrontrunningProtection](https://github.com/flashbots/rpc-endpoint/blob/e01c72732ff88b58cca8ad1de6468e7ccf3577aa/server/request_sendrawtx.go#L176) only logs the gas usage but doesn't check that the gasLimit is > 42,000. I also ctrl-f'ed the repo for `42000`, `42,000`, 42_000` and couldn't find anything.

Is the readme bullet point still accurate?
