Only at the point you want to interop with that legacy world. Skype did a
pretty good job of avoiding the legacy and changing users expectations of
telecommunications.

If there is a market for interop (which there clearly is) then multiple
vendors will no doubt offer gateways. I'm just concerned that we are
talking about imposing legacy requirements on the core API, when WebRTC
seems an ideal opportunity to break away from that legacy.
