Obviously :-)

I'm not sure about it.  I mean, yes, it's simpler - it's actually possible
to understand and remember how it works now - but from what I remember,
the problem with the old semantics and libarchive was that libarchive tried
to set file mode after restoring the ACL.  With draft semantics, this
resulted in malformed ACL.  With PSARC semantics, this results in no ACL
at all.
