To the extent people relax their superstition, they advance towards personal freedom (unless they latch onto personality cults/secular superstition, see "North Korea").
Unreformed primitive groups may evolve as their members are replaced, but that's not a reason to respect their beliefs, or respect them, at all. They can wake me if they "modern up".
No, it can inform policy. For example, decisions not to intervene during transitions. Giving up intervention against Bolshevism saved resources and allowed the decadent Tsarist regime to be swept away. Not intervening in China also meant not creating a permanent enemy thus facilitating (thanks be to Richard Nixon) detente.
In both cases backward cultures were moved forward by internal revolutionary force, and rotten institutions were destroyed along with their "human obstacle" supporters. Colonialism could not have accomplished that level of rapid reset, which also eased transition to secular Capitalism.
I favor facilitating disruption by inaction or calculated action rather than invading to impose "order". It's cheaper than fighting barbarians, and when the make their states unpleasant enough their own people may rise and try to kill them.
I also favor actions to reduce their influence in modern countries. For example, the Islamic superstition is currently as toxic as Bolshevism. Make its adherents uncomfortable enough to stay in "historically Muslim" countries and plink each other instead of spreading their restrictive superstition (which in all its variants fails to offer me the level of personal freedom I require from a society) by spreading themselves elsewhere. Don't offer a "safety valve" for their regimes in the way immigration FROM Cuba is the "safety valve" which maintains Castro. Immigrants from Cuba normally reject Communism, but superstitionists only move for economic reasons and merely spread their contagion.
Disruptive change is often healthy. I'd like to see Iraq fragment and the Middle East plunged into as many wars as possible. It's the price of progress. Nothing in the region couldn't use a good smashing. It took centuries of war to (mostly) sort out Europe, considerable war to sort out China, but the tiny wars of the Middle East are insufficiently disruptive so far.
