Right, adding xattr support would require changes to 5 or 6 different
kernel modules (linux/freebsd/netbsd/windows/solaris?), and some of
these might not even have xattrs to begin with (windows?) requiring an
alternative approach.

But everwhere we already have and support pioctls, the only places where
that breaks is when you try to run a Linux venus binary talking to a
NetBSD kernel module, but it was never designed to do that in the first
place. It used to break at the first 'ls' because the kernel module used
to leave directory parsing up to the VFS and we used to have a different
directory container file on each platform.
