Gradient-based steering like ReFT may remove the need for localization

arunasank responds to johnhewtt: behavior is evidence that mediators are effective, and gradient-based steering methods like ReFT (from their paper) work without needing localization in limited settings. The exchange touches the core tension of johnhewtt's blog on separating forms from estimators — interpretable localization+steering vs. direct fine-tuning.
