The project is still underway, but I think decoding is more important than encoding, especially with live streams. Given a Twitch stream, for example, the encoding is only done by one peer while the decoding is done by thousands or (as of recent) millions.
Efficient encoding is very important for WebRTC and video communication in general. And AV1 is proposed for it. So hopefully some major improvements are planned.
I believe that in that context "performance" refers to encoding efficiency (aka compression factor), not the encoding or decoding speed.
So not a good format for live streaming then?
Bitmovin produced an AV1 live stream a year ago using 200 cores: https://bitmovin.com/bitmovin-supports-av1-encoding-vod-live...
And six months ago they had improved on that to do live streaming with 32 cores: https://bitmovin.com/constantly-evolving-video-landscape-dis...
Twitch wants to use AV1 for live streaming. Here's a talk on the "switching frame" feature of AV1 for use in live streaming: https://www.youtube.com/watch?v=o5sJX6VA34o

Counter-argument: encoding is the bottleneck in live-streaming

Bitmovin and Mozilla recently also did a Webinar about AV1: https://bitmovin.com/an-introduction-to-av1/
>The Twitch test set is entirely live-streamed video game content, and we see solid gains here as well.
From the article, near the end.
