The problem is the antivirus software, not the kernel features that the AV software is using. I can't imagine that MS would cripple their OS just so that someone who mostly uses WSL can bypass the AV software that their sadistic IT people force them to use. The only solution there is to just not take jobs where someone can force you to use such machines.
Try creating a lot of small files, even microsofts own antivirus (which seems to be the most light weight of the anti virus alternatives) adds significant overhead. I know its not a simple problem, but since most large repos contain a lot of small files this does create a negative "workstation os" image for windows in my mind.
