We also need to flip the various review gates on the chromestatus entry
(privacy, security, enterprise... etc.). If you're working with someone
at Google on this feature, perhaps they could assist?

Specification
https://w3c.github.io/webrtc-extensions/#dom-rtcrtpreceiver-jitterbuffertarget
Summary
JitterBufferTarget attribute allows applications to specify a target
duration of time in milliseconds of media for the RTCRtpReceiver's
jitter buffer to hold. This influences the amount of buffering done
by the user agent, which in turn affects retransmissions and packet
loss recovery. Altering the target value allows applications to
control the tradeoff between playout delay and the risk of running
out of audio or video frames due to network jitter.
Essentially it is a rename of already shipped playoutDelayHint attribute.
Is this purely a rename, or are there changes to the semantics?
And do we have any sense how widely used playoutDelayHint is in the
wild? There is some discussion of the bikeshedding in
https://lists.w3.org/Archives/Public/public-webrtc/2023Apr/0045.html,
but no consideration of existing usage (at least as reflected in the
minutes).

WebView application risks
Does this intent deprecate or change behavior of existing APIs, such
that it has potentially high risk for Android WebView-based applications?
None
Debuggability
None
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?

Anticipated spec changes
Open questions about a feature may be a source of future web compat
or interop issues. Please list open issues (e.g. links to known
github issues in the project for the feature specification) whose
resolution may introduce web compat/interop risk (e.g., changing to
naming or structure of the API in a non-backward-compatible way).
None
