@xbolva00 Are you specifically aiming to get this in for 14.x? TBH this close to the branch date, I'd prefer to delay this work until the branch is made and initial cherrypicks are out of the way, and we aim for 15.x

We've tried similar things to this in the past and its taken a long time to get it stable (usually by disabling it a lot of it).
