If the original code wasn't broken and the new code produces the same output, I'd really not mess with this code. There simply is no upside to messing with this code. It's run once during boot and never a noticeable contributor of boot overhead. Maybe the new code is a bit simpler and more efficient but the actual benefit is so small that any risk would outweigh it.
