The current back-ported feature isn't the default or used for the root
file system.  Users have to "opt into" any conformance bugs it may
have.  (As they can also "opt into" non-conformance by specifying
non-default mount options or third party file systems.)

If ZFS root becomes the default, then I agree that Don has a point
here.  However, in 2006/370, it seems to me that Live Upgrade requires
new options in order to do the migration, and jumpstart requires a new
keyword to enable ZFS at install time.  It doesn't appear to be the
default.

It's thus still an opt-in feature.  Perhaps it should come with
advisory information that only UFS is UNIX branded and/or strong
advice that whatever remaining compliance nits exist ought to be swept
up.

This has everything to do with making sure that we don't lose S10
branding.  I don't think it has anything to do with making an "example
of" some feature.  I'm not even sure I know what that means.
