I am only going to speak to the use of "legacy" in this conversation.

What is referred to here is a specific ZFS idea and should not be
confused with any sort of global notion.  Specifically, ZFS, by default
and in common use, does not use anything like a /etc/fstab or
/etc/vfstab to specify where the filesets get mounted.  It also does not
usually use the usual mount command either to mount them, although that
would work in Solaris if I remember correctly (at least in some cases).
What happens is that the mount point is specified in the fileset meta
data and "zfs mount ...." takes care of getting it mounted.  If you
wanted to use /etc/fstab or /etc/vfstab with ZFS you need to mark the
mountpoint in the fileset as being legacy, then you could fill in your
/etc/... files as you wanted.  This, of course, strongly suggests that
Sun was going to make all of the other filesystems except ZFS second
class, but Sun fell apart before that really progressed to anything
final and Oracle never really ran to that conclusion either.  No one is
at all suggesting that any filesystem become second class in the NetBSD
realization of ZFS.

So the term legacy when speaking of ZFS is used to refer to a filesystem
that uses whatever /etc/... files you use and uses the usual mount
command.
