I believe the commit you're looking for is this one: f338a5c870a36e493f8c818fa783942d1e0565a4

There the scrubber queue was switched on purpose, which leads to the
conclusion that we're moving away from it. I've not participated in
discussions around the change related to the scrubber queue so I'll
let Zhi Yan weight in here.

Thanks for bringing this up,
Flavio

P.S: Would you mind putting a link to this discussion on the spec
review?
