It has been like that for I'd guess 15years and to change it
would be what FreeBSD calls a POLA violation, I think?
(The Principal of Least Astonishment implies that things
don't change when people go to new releases. The new releases
may have new features, but they aren't enabled by default when
the new release is installed.
At least that is my understanding of it. For example, an NFS
mount still defaults to NFSv3.)

The default for UFS is no ACL support, with POSIX draft ACLs
or NFSv4 ACLs being enabled via mount options. and has
been that way for at least 15years.
