Specificationhttps://www.rfc-editor.org/rfc/rfc8826#section-4.3.1

Summary

The SDES key exchange mechanism for WebRTC has been declared a MUST NOT in
the relevant IETF standards since 2013. The SDES specification has been
declared Historic by the IETF. Its usage in Chrome has declined
significantly over the recent year. This intent is to deprecate and remove
this code from Chromium and WebRTC.

<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EWebRTC%3ENetwork>

Motivation

The reason why SDES is deprecated is that it is a security problem: It
exposes session keys to Javascript, which means that entities with access
to the negotiation exchange, or with the ability to subvert the Javascript,
can decrypt the media sent over the connection.

Debuggability

When this feature is removed, people attempting to set up such a connection
will fail to do so. This should be easy to diagnose.
