Best practice question: DKIM AND DomainKeys?

I was running some deliverability tests today sending to Yahoo accounts, and
a look at the headers inside the Yahoo Mail client showed the following

domainkeys=neutral (no sig);; dkim=pass (ok)

I realize that DKIM is a newer standard, and that DomainKeys will likely
fade away soon enough, but since there are large mail providers (like Yahoo)
that still check for a valid DomainKeys sig, is there any benefit to having
OpenDKIM sign with BOTH? Any drawbacks?
