This is a request for Safari to implement the selectedcandidatepairchange event on the RTCIceTransport interface. This would be useful to track connection type changes, for example moving from TCP to UDP, or from TURN to srvflx. In addition, the getSelectedCandidatePair instance method should be implemented alongside this change. Browser support is basically Chromium-based ones have it, and nobody else yet. Given Safari's size on mobile this would be a great addition!
