I see that in the develop branch of the magento 2 repo the methods [`load`](https://github.com/magento/magento2/blob/develop/lib/internal/Magento/Framework/Model/AbstractModel.php#L523) and [`save`](https://github.com/magento/magento2/blob/develop/lib/internal/Magento/Framework/Model/AbstractModel.php#L625) from `Magento\Framework\Model\AbstractModel` class are deprecated.  
But there are a gazillion classes in the core that extend this class and use `save` and `load`.  
When creating my own module for the CRUD part of my entities I follow the same guidelines as a core module does.  
But since these methods are deprecated I would rather be prepared for the future.   
What should I use instead of them? Or I should extend something else?
