Why? AFAICT the only differences between FFSv1 and FFSv2 are that the
metadata takes up twice the space on FFSv2, and that newfs is faster on FFSv2.

Nope, you need to run newfs and then restore a backup.

It didn't, although someone has added fs snapshot support to NetBSD which,
IIRC, covers UFS1 and UFS2.
