I am not sure what ffs_oldfscompat_read() does, but several people (me
included) have now unmountable disks that used to work fine in production
before, and it is not quite clear what causes the inconsistency, see
the thread at

https://mail-index.netbsd.org/current-users/2015/04/30/msg027310.html

I am pretty sure (but not 100%) that my root filesystem in question has been
created past the newfs change cited in that thread, but it is clear that a
-current newfs would not trigger the issue.
