why: For the main tree with root vertex ID 1, the leaf nodes hold the account data. These accounts may link to sub trees the storage root node ID of which must be registered here. There is no reverse key lookup on the backend. note: These definitions are experimental. Also, there are some tests missing for validating Payload data conversions.
