Does it matter? When I walk into a building I don't get to tell their IT guys what protocols to use and which to avoid. I don't get to tell them my own preferences and make them conform to them. I don't get to start a job and demand they change everything about everything on day 1. I adapt. And if they're using NFS, I want to make sure I can use NFS too. That's why fixing this bug was important.
