why not fuction instead of method?

Because of where it is being used. The List method was added to the Policy Interface as it required in the mapping functions.

The bad smell is that you are not using the receiver, thus looks like a dog, walks like a dog and barks like a dog, but it is a cat. (dog => function, cat => method)

One of the previous iterations of this PR did not have this. Instead it listed the policies from the cluster based on the type passed in. There was a switch within the mapper function. It was suggested that this was the cleaner approach. I understand why you don't like it.

The method could have been name sth like ListAllOfKind.
