Unfortunately, if "people with high credit scores have less insurance claims," then preventing insurance companies from taking this into account is a deadweight loss to society.
People who are more likely to have more insurance claims should pay more for insurance (that's the whole point of underwriting), otherwise people who are less likely to have claims are being unfairly overcharged.
Now if you take a look at how many people got hits to their credit score thanks to the recent government shutdown or due to massive medical bills or due to identity theft/other fraud, things look differently.
Credit scores deserve to rot in hell forever. Humanity has managed to exist for thousands of years without this degradation of human worth to arbitrary totally intransparent numbers.
