Your analysis and approach make sense to me, even though it's
regrettable that it is necessary.  I guess UFS needs zfs-style feature

What about compatibility with FreeBSD?

  - What happens if someone takes a FreeBSD UFS2 filesystem and mounts
    it under NetBDS 9?

  - What happens if someone tries to mount a NetBSD <=9 UFS2 filesystem
    on FreeBSD?   A 10 UFS2 filesystem w/o ea?  with?

Or is it already the case that FreeBSD and NetBSD do not interoperate
with UFS2?

And same questions for the other active BSD variants, which I think is
mostly OpenBSD and Dragonfly these days but I have lost track.
