Get OrgContacts delta with their Addresses and Phones

Currently, the Get OrgContacts delta Endpoint 

https://graph.microsoft.com/v1.0/contacts/delta

Does not return the Contact's Address and Phone, and we are forced to call the 

https://graph.microsoft.com/v1.0/contacts

endpoint to get this information. 

It would be great if the GetDelta supports Addresses and Phones.
