We would like to get an official position on the addition of adaptivePtime flag in RTCRtpEncodingParameters. Enabling the flag allows a sender to dynamically adjust the audio packet rate to better utilize the network link.

Explainer: https://w3c.github.io/webrtc-extensions/explainer#a-new-flag-in-rtcrtpencodingparameters-for-adaptive-packet-rate

Spec: https://w3c.github.io/webrtc-extensions/#dom-rtcrtpencodingparameters-adaptiveptime

The flag is currently available through an origin trial in Chrome (https://chromestatus.com/feature/5752004691361792).
