It is encouraging to see new features being explored but limiting access to the proprietary OBS connection is unfortunate.

Ideally, the ability to send multiple streams would not be gated behind the proprietary OBS connection so that advanced users could configure their stream pipeline to take full advantage of the latest features.

This would be particularly helpful for stream broadcast suites or users that run their own rtmp relay.

For example, a user might leverage SRT to a cloud server that transmuxes the streams to rtmp to get around local or mobile network inconsistency.

If they could manually configure streams to known endpoints at Twitch they could push one stream to their relay and have the cloud server transcode and deliver various qualities even creating the 9:16 vertical orientation.
