No since I don’t know of anyone doing rerun’s. We stopped due to poor support for them on Twitch and situations changed.
And if the stream shows in search, how do you know it’s a rerun? Just becuase it doesn’t show on /streams/ doesn’t mean it’s a rerun. So you are making an assumption which might not be reliable. Since there are other things that might make a channel show as live in search but not show as live on streams.
ReRuns need to be treated like a “regular” stream and surfaced as needed to the right endpoints.
