We want examples of both prioritisation between causes and prioritisation between interventions, but cases of the latter are far easier to find—like PlayPumps the examples you give. I actually think the former is a more important EA insight: it would probably be more valuable for the world for people/resources to focus on the most pressing cause areas, rather than to do what we currently do more (locally) effectively.
Thanks. The nuclear one is a great example.
