Because SOA does not now normally appear in the Additional section, and because the Additional section does not normally have RRSIGs. Proposing a new EDNS0 option causes much less epistemological grief than extending the semantics of the Additional section.

Having said that, I believe that a possible draft-ietf-dnsop-additional-section-as-kitchen-sink is actually a good idea. If the WG like it, "SOA of this response" and "signed SOA of this response" would certainly fit there.
