I think we can divide Repository interfaces into multiple interfaces.so Extension providers don't need to provide implementation for all methods in interfaces.
interface CustomerRepositorySaveInterface
{
/**

* @throws \Magento\Framework\Exception\State\InputMismatchException If the provided email is already used
* @throws \Magento\Framework\Exception\LocalizedException
*/

{
