There is no harm if they do. The problem is the root servers
themselves being unable to put out full sets of A records for the
NS'es for "." without overflow. If your local name server has all of
it, there is likely no harm. We especially don't want people doing TCP
based queries against the roots.
We've already been told, by the way, that older versions of BIND won't
cache the AAAA/A6 records at all.
