I believe the last time this came up, i asked for a rationale or
explanation.  The only reason given [0] was from J. Bruce Fields:

So, if you have no v3 clients, i don't think there is any reason to
avoid fsid=0 if it makes things cleaner for you.  And removing fsid=0
will require you to change /etc/fstab (or your automounter config) in
all of your clients.
