Do resource interfaces have to be interfaces?
Hi! I've followed the documentation while creating a Refine app and when I sent it for review one of reviewers(my coworker) told that the interfaces(the ones that represent resources) are not actually interfaces, because they are not used in our app to implement any classes. This means we can actually change them to be types and not interfaces. So the question is: why does the documentation has them as interfaces? Is it a requirement?
