I'll work on gathering more data for other systems. So, I'd suggest two phase action. 1. Commit your patch, but disable by default. 2. Gather more use-case and performance data. Note: They should be reproducible. We need measure them again and again when libs updated. 3. Change the default when the community is convinced the benefit.
