Richard,
what you mentioned is implemented on the product side (IPAM/UDT). SDK just provides interface for working with CRUD, Verbs, etc... New SDK versions are mostly about bug fixes, documentation updating and new implementation for product needs (e.g. new types of parameters, connections, ...). As well as the the verbs, also the CRUD operations must be implemented on the product side. In case you're interrested in something special, raise the ticket or thread in the product space.
Thanks.
