It's not clear to me whether you mean 'full-function' or 'stub'.
Either way, I'm not sure. The synthesized-on-the-fly CNAME tends
to mask any deficiency in this area.
I do know that BIND has had it for quite a while.
I'm led to believe that a resolver can't properly support DNSSEC
unless it supports DNAME. I haven't fully understood the argument,
but understand that some unacceptable corner cases arise otherwise.
