This is correct.

Additional section processing has been useless for a while. It turns
out that it is very difficult to make use of data in the additional
section in a dual stack environment because lack of A (or AAAA) RRs in
the additional section for a MX DNAME does not mean that these records
do not exist in DNS. Consequently, you need to perform an additional
DNS transaction anyway in many cases.
