I think we are happy with where things are at, significantly very positive in some of the streams/gatherer tests. The Starvation test is the canary to catch a scenario that has been observed along the way, but not with the current version. So I think this is good to integrate.

Seconding @AlanBateman, I've reviewed and provided feedback on this PR multiple times, and have had numerous runs of parallel streams / gatherers and I think this is good to go. If I was a reviewer my vote would matter, but I'm adding this comment here as an "enthusiastic supporter". :)
