I have a situation where the ShippingProvider can return an accurate rate estimate if the region is included or a less accurate estimate if the region is not included. I am going to let the merchant decide if the region is required or not. This will be stored in the local component settings for the ShippingMethod.


I would like to write my ShippingProvider.RequiresState override so that it looks something like:





That means that I need a way of telling the ShippingProvider which set of component settings to use. One suggestion is to add a property (i.e. provider.Method = method). Another suggestion is to change all the "Requires" properties to require a ShippingMethod argument (this would logically match GetRates which requires the method).



I think they would both require about the same amount of coding changes, though the second would temporarily "break" existing 3rd party providers (which would be OK with me).
