Currently, in v2, we set a class using AvroSchema and AvroLogicalType annotations to be able to customize the final schemas and add logical types, but this requires kotlin reflection to allow creating the instance of the given class. In v1, we unwrap the nullable SerialDescriptors to get back the AvroDescriptor to access the custom methods for generating the schemas.
A PR has been done to be able of unwrapping a nullable descriptor, that now allows us to retrieve the original descriptor, so we can get rid of reflection for logical types and custom schemas, and it allows us to create brand new methods and interfaces on a standard SerialDescriptor.
