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

[samlaf]

The README, in this section, 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 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?
