This is something we get "for free" with the "WebRTC-AllowDisablingLegacyScalability" field trial that has been wired up to support VP9 simulcast. This test works and passes, however the ramp-up time is pretty bad. - VP9 simulcast takes approximately 4 seconds to ramp up. - VP9 SVC takes approximately 16 seconds to ramp up. - AV1 simulcast takes approximately 22 seconds to ramp up. A TODO is added (webrtc:15006) and the test is given extra timeout, a full minute to get bytes flowing on all layers. Despite ramp-up being bad, it's important to test that AV1 simulcast is in fact working to avoid regressions due to obsolete assumptions about which codec do or do not support simulcast. AV1 simulcast is an opt-in feature so there is no harm in the API not being perfect yet.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
