I don’t think it’s necessarily clear that incorporating moral uncertainty means you have to support hedging across different plausible views. If one maximises expected choiceworthiness (MEC) for example one can be fanatically driven by a single view that posits an extreme payoff (e.g. strong longtermism!).
Indeed MacAskill and Greaves have argued that strong longtermism seems robust to variations in population axiology and decision theory whilst Ord has argued reducing x-risk is robust to normative variations (deontology, virtue ethics, consequentialism). If an action is robust to axiological variations this can also help it dominate other actions, even under moral uncertainty.
