Extension of the fields mapped for MembershipState

[lucaalbinati]

In the MembershipState data class, in the generateMappedObject function, why doesn't it map all of the fields?
Why does it only map member, bno and status?
It would be useful to also map the rest of the fields, especially membershipMetadata. But because it currently extends Any, I understand this would be a problem, but by giving it a base class (like the SimpleMembershipMetadata), it could map some of its fields as well.
