SDP is a session description protocol, not an addressing protocol. WebRTC will be able to use IPv6 addressing in future, too, and supporting IPv4 where possible means it's practical to use now as well.

SDP is most certainly an addressing protocol. It's a very complicated one that uses many binary tokens including IPv4 addresses (or IPv6 adddresses) and port numbers, cookies, and keys.
That some of the binary tokens used in the SDP addresses are discovered using ICE/STUN (sometimes) complicates service providers greatly.
