I know it was briefly enabled by default, which was reverted due to correctness (or was it regressions?) problems. But if this belongs in GVNHoist, could this for example be added to GVNHoist, and only this part enabled? Not sure if that's possible as I haven't looked at GVNHoist.

Yes, GVNHoist will do what we need
