As a Brit, I prefer not to have that comma. It just feels wrong to me, I was always taught not to use it. I'm hoping there's a way to remove it using this system. Intl.ListFormat('en-gb') perhaps?
"tabs vs. spaces of writers" explains a lot 
I prefer Oxford comma as well but couldn't care less if I use it or not i.e. someone doesn't want them in their documentation...I just don't use them, super simple lol
