They have them for ages.

Perhaps it was bad wording on my part.  I meant support for ACL and
extended attributes in coreutils.

It was poor wording.  Other distros fully support ACLs and xattrs.  And
a project of mine relies on both these features, so that was the reason
I wanted to introduce these two packages into Owl.

Yes, you are correct.

These tools allow one to fine tune file permission beyond the standard
Un*x model of owner, group, and others.  For example, you can (as a
non-privileged user) grant access to a file/directory to another user
and/or group.  You also can configure default permissions for user/group
on a directory so any file created there will inherit the defined
permissions. This was about filesystem ACLs.  With extended attributes
one can attach metadata to files/directories.
