It's actually rather beneficial and important. There are a few posts where people removed it and alternator died in high demand cars. I know the Technik ASA supercharged cars because of piping left this off. Several owners noticed their alternators died soon after. So a reroute and ducting of cool air back as originally designed by BMW was done.
It's often not noticed how important some designs are until when removed the difference they make.
